My thoughts on this are with kids as they grow, there comes a time when you have to trust them, that trust changes as they grow older and/or mature. No matter how much we try, kids are going to slip and fall, they are going to make mistakes, it is part of growing up. The tricky part of course is always “how much”, and with our S it was always “as much as we felt he could handle, was ready for”, which of course is totally unscientific, totally by the gut, and certainly isn’t failproof…and it is why there is no one right answer, every method of parenting, every decision you make as a parent has consequences, seen and unforseen, and you do the best you can.
There were times when we said no to our son with things (not like this scenario, his world was very different than a typical high school kid because of music), but there were times when he wanted to do something and we said no because our gut said it wasn’t good (primarily because we believed that he would end up getting hurt emotionally). We had things we said yes to that now looking back we wouldn’t do again(like my son at 11 attending a music festival where most of the kids were older high school and college age), but he learned from it as did we.
My mom always said that once a kid hits 15, 16 there is very little as a parent we can do to shape them, and while I don’t totally agree, I agree there is a point where we have to learn to trust them and our judgement and yes, let them take the consequences of their actions. So taking the example of a party when the kid is 18, so as a parent you say no, afraid of the consequences of it (drinking, sex, etc)…but what happens when they are 18 and away from home, has saying no done anything towards making that less risky? (and again, this is just my thinking, it isn’t criticism of those who might say no…:).
The kid will have to jump at some time, and I like what @SouthernHope did, gave him parameters she felt safe with but let him make up his own mind, and also got something back for him (letting her know when it was over, so she wouldn’t fret, that showed respect for her feelings)…and like Reagan, also had a bit of “trust but verify”…and with her approach @SouthernHope also if this goes well, gains a piece of mind that when her S is away he will know how to handle himself:).
My S is getting ready to graduate from conservatory this year, and guess what, he has done some dumb things, that had consequences including a medical scare caused by doing something dumb, despite what we tried to teach him, but that is life, you make mistakes and learn from them. My take is hopefully by allowing kids to take chances as they grow up, by giving them as much leeway as you feel comfortable with while remaining a parent, if the kid does make mistakes they won’t be the major ones we fear (serious illness, injury, legal trouble) and ones they can recover from, and of course we still can be there to help when they do slip.
I’ve done the best I could with my children and try to set reasonable parameters. But they know I will be that parent who calls the police and hires a really good attorney to pursue charges if things go down wrong. It is going to be a painful lesson for all involved. As far a graduation party, we can host for our child and his friends at a restaurant and stay out of the way.
