I’ll start.
My sister told me the toilet paper I was using (Scott’s – 'cause a thousand sheets lasts longer!) felt cheap and discount-y, and that I should upgrade to Charmin or something similar.
I told my sister that she needed to upgrade her undergarments, because she was looking lumpy and bumpy under her clothes.
I also told her she needed to upgrade her guest room pillows, since the ones she was using were from before World War One.
I told my best female friend in high school (I’m male) that her moustache was kinda noticeable. She was aghast and walked off. I’m sure I could have been more sensitive about it too (I was in HS, after all!). But she got it fixed, that’s for sure!
We were (and still are) super close after +30 years!
That how my husband dresses is no reflection on me.
My best friend from 6th grade was engaged at 24 and planning her wedding. She asked me, a bridesmaid, what I really thought of her fiancee. Since we had all been in HS together, I asked her if she wanted my honest opinion.
She did, so I told her she could do so much better and not much worse. He had no ambition and wasn’t interested in anything intellectual. I thought she would ultimately be bored and resentful of him, ending in divorce.
She broke the engagement the next week, married a great guy 10 years later. Her parents later thanked me. We’re still great friends at 60, though we live 1000 miles apart.
@VeryHappy I like Scott tissue because it’s less soft.
I wish I could redress my sister she’s been wearing the same unflattering t-shirt cotten dresses for the last ten years to Thanksgiving. They make her look less dressed up not more dressed up. I tried one year to get her a better looking sweater, but she returned it. They look like this with blander colors: http://www.cathkidston.com/cath-kidston/hedgehog-spot-dropped-waist-dress-1019008
^^^Another vote for Scott! I prefer it AND it lasts so much longer!
My sister and I aren’t particularly close. But this week she called me after the OSU incident because both of my girls are nearby to OSU. She reminded me that physical scars can heal but we need to take time to make sure emotional scars have time to be exposed and to heal. And that even if you aren’t close, she taught me it’s things like her call that make you closer. <3
We use Scott here too. It’s less soft because it’s only 1-ply and therefore less likely to clog a toilet. A plumber friend told my mom that years ago and it was very good advice.
In college I was dating, then living with a guy who did not treat me well. A friend from my major who was in most of my classes but didn’t know all that well happened to be sitting next to me at the pre-graduation party our cohort was having. My BF came in, yelled at me to find my own way home and stormed out. My classmate looked at me and said, “You don’t have to put up with that. You have friends who can help you, including me.”
It took another full year before I got my act together and moved out, but the seeds were planted that night by my friend, who let me know without judgement that I wasn’t alone. We’ve long since lost touch, but I’ve never forgotten how important it can be to just let someone know you’re there for them.
Re toilet paper: I started out by using the Charmin only in the guest bathroom but then I kinda started to like it.So now it’s in all the bathrooms.
People who tell you things honestly that no one else will tell you are, IMO, priceless.
Ha! I had a good friend in the 90s tell me A} that I was now old enough to join her in the search for stray chin hairs and B} that women’s bums drop after 30 and don’t look so cute in leggings anymore, but of course that was before Lululemon brought out their bum lifting yoga pants!!
I need to tell my sister that her super comfy ‘don’t bind’ bras also don’t lift and make her look old and lumpy. She is on a diet so when she reaches a milestone and it’s time to think about some new stuff, I think that will be a nice time to chat.
I have a heavy-set friend whose boobs are down around her waist but I don’t know her well enough to tell her she needs a good bra fitting. It would make her look so much slimmer by defining a waist for her.
A brother not a sister…
A few years ago, at a family get-together, one of my brothers asked why I didn’t have on my Uggs (like all the females in his family) since I’m always so cold and I confessed I didn’t own any. I didn’t mention it was because they aren’t my style. Soon after we all returned home, he sent me a pair. Very unexpected. My husband said they weren’t my style and so ugly, but it was such a thoughtful gift that I thought I’d just wear them around the house and use them for slippers. (My husband found it amazing I was wearing them at all) Those Uggs really changed my life. My feet are warm for the first time ever. I have never worn them out of the house yet, but I may get there. I’m wearing them right now.
life changing advice 
eta:
my sisters told me for a decade I should be coloring my gray. Finally the color turned out pretty good and now they tell me not to dare cover it up with dye. I can’t think of any other advice they have ever had for me.
Usually they are calling me to ask what to do, because I’m eldest. It’s not cause I know more, just a habit.
I told my sister not to get married, that it was better to break off an engagement than a marriage. She was very very angry with me. She did marry him and he killed himself 14 months later, stranding her with income tax that he’d cheated on, leaving her to deal with the IRS for the next 10 years. A single tax return filed jointly. Only when the innocent spouse laws came into being was she relieved of that burden.
BFF told me to quit being cheap and to accompany ds1 on his final college visit so I could see where he’d likely be living for the next four years. I’m glad she did. I loved the school as much as I hoped I would and felt no qualms that fall moving him in.
Also, someone on here – I don’t remember who – gave me grief for saying I couldn’t afford to get my kids braces. He/she talked about how poor teeth will always be a marker of being lower-class and would hamper my kids in the future. I cried when I read that and was furious that someone who apparently didn’t need to worry about money was lecturing me on how to spend the little I had. It was a struggle, but I did get my kids braces and am glad I did.
I’m chuckling at some of the “don’t marry him/her advice” because a sibling of my spouse told him not to marry me a week before our wedding. We’ve been married for over 30 years now with 2 wonderful kids. Meanwhile, that sibling has been divorced twice. Not all advice like that is good nor welcomed advice. 
My H was warned NOT to marry me by one of his loved ones. My family wasn’t keen on the match either. We have just celebrated our 30th anniversary and couldn’t be happier.
I never understood the point of cheap toilet paper. I just use more of it! I use Charmin all the time, the meg rolls that don’t have to be changed as often.
Yes, I much prefer softer TP–one of life’s little luxuries that definitely make life more comfortable.
“Yes, that dress makes your butt look big.” (In dressing room prior to purchase.)
“Your kids are old enough to walk around the neighborhood by themselves. Your fears are irrational and are harming the kids.”
“If you keep treating your husband that way, he’s going to leave you one day.”
“Charmin’s texture is unpleasantly linty. Triple-ply Quilted Northern is the only way to go.” (Ok, I’ve never actually said this to my sisters or best friend.)
Divorce him–advice from bff (I don’t have sisters). She was right.
My parents were the cheapest people on earth–after they passed away and we were getting their house ready to sell, my brother found 3 cases of Scott tissue.
I love the discussion of toilet paper woven through this other discussion.
