Bridesmaids in cowboy boots at weddings. It was tacky to begin with and it’s been done to death.
Marriage proposals conducted as big budget Hollywood productions and promptly posted to YouTube.
Hockey - high school hockey around me is a cult.
Videos of returning soldiers surprising their families.
^Agree about the soldiers. I think it is so intrusive, especially for the kids who burst into tears in public, I do like the dog reunion videos, though. 
^^^
I love most of those videos – they make me cry sometimes. Having said that, a few of them seem “staged.” But the authentic ones really get to me – these kids really miss their dads.
LOVE the dog greets soldier ones. I even saw one where there was a cat freaking out and jumping into his soldier owner’s arms, and this big tough guy was kissing him all over his face. 
Marriage proposals conducted by soldiers at hockey games with the girl wearing cowboy boots and she’s majorly surprised because it’s a first date. And there’s a dog in there somewhere. I hate those.
Obviously feeling curmudgeonly today:
Promposals
Baby gender announcement parties
Bah humbug.
This admission will undoubtedly get me flamed , but here goes :
Pit bulls. Too many people breeding for the wrong reasons and they are overcrowding shelters. The well meaning people who adopt them with no clue how to handle them. The people who always blame the owners when they attack humans or other animals.
I think they look like gargoyles and I don’t trust them, largely because they are over bred by idiots who shouldn’t even own a pet
Wow! “A Confederacy of Dunces” Everyone I have met that hates this book IS the main character.
My friend gifted me with a beautiful Vera Bradley backpack, It is black leather with white piping and the inside pattern is black and white four leaf clovers, very subdued and professional looking enough that I can wear it to court. Otherwise, I agree with what you say about the patterns.
@lje62 - I 100% agree about pitbulls. We used to live down the block from one. I never left the house without a bat in my hand or the stroller. I used to take the children and run them out to the car, one by one, and lock the door in between. The dog scared the living daylights out of me.
“Promposals”
I understand where you are coming from. I thought they were idiotic. But I have to say my daughter’s promposal was super sweet and touching (he enlisted a bunch of friends to give her a message about why he was so happy theyd become friends before each class that they read aloud. The last one was " Because I have a great girl to ask to a Prom. Will you go with me?" .) She was super embarrassed but at that same time really like it. Her teacher said it made her almost cry when she heard one of them
E-vites or any email invitation, especially the ones I have gotten that won’t print out. I like to have something to put in my “book” or on the fridge. The ones I have received (and I’m sure there may be several companies) would only print out with text out of wack and on multiple pages. The concept I’m ok with…I guess
I also dislike promposals and actually don’t like marriage proposals that are a whole production.
I don’t like Halloween. I hate getting up every time the doorbell rings. I hate the slutty costumes for 10-year-olds. I hate teenagers who come to the door without costumes because they want free candy. I’m Halloween Scrooge.
Regarding promposals, I see how they can be sweet, but I wonder how hard it must make it to say no. I think about some unsuspecting girl in the school cafeteria, just having lunch, when some guy comes up with flowers and teddy bears and a big glittery “Prom?” banner, and five of his friends filming and everyone watching, and she doesn’t want to say yes. Poor girl.

Wow. That would be bad but it does NOT happen here. Every person who asks ( unless its their boyforend/ girlfriend) does a “pre-ask” which means he or she seeks out a friend of the " askee" and the friend then says something along the lines of " hey Schuyler, Devon was wondering whether you’d want to go to Prom like if he asked you" if it’s a no the friend merely tells the “ask-or” “um I think he/she is already planning to go with someone” or something like that.
The Promposal comes a different day.
Agree about Halloween. Did it for years when my kids were trick or treating but they don’t anymore so all you little ghosts and goblins take note; there’s no jack-o’-lantern and the porch light is off. Just keep moving.
^Go away, I am in here eating all the candy myself. 
OK–I can deal with Halloween. I HATE Thanksgiving. I feel guilty even writing this. We have lovely friends
and we have been together the last 18 Thanksgivings They are great. I simply hate every bite of the food.
Cannot stand turkey. I do not care about mashed potatoes, her family stuffing is bad and what she stuffs
the turkey with is worse. She uses no salt or seasoning. The stuffing is bread and broth basically.
Everything is always cold. I bring lovely green beans and such but not so great cold.
The H makes canned pie filling topped with canned whipped cream. There is another pie but I do not
care about sweets. Games. AND it is always always cold and raining and we are stuck in the house for
hours. Groan. I love them just not the food or the holiday.
^^ @oregon101 life is too short for crappy holidays. After one too many dismal thanksgivings where MIL had a temper tantrum over something or other, we now go on a cruise for Thanksgiving. Sunshine, people waiting on us hand and foot, and no stress. We wonder why we waited so long. If you are not loving it, then stop doing it.
