At my Catholic school the popular answer was until college age, which is about 18.Why in the fokk would you want to encourate teenee-weenies to interact like that?As a parent. I knew the boys and girls go to the mall to meet the opposite sex. If I had a teenage girl going to the mall right now, I would go with her to make sure she would be safe. If they can't take a parent, then get another adult.I don't know. I guess if your kid goes and does some shopping and is well behaved, then you might be upset about these kind of rules. It's probably the minority of kids who rampage at the mall. I'm sure most of them (especially the girls) are there for the shopping.
Don't you want your children mingling with the opposite sex? They will be socially inept if you don't allow them to be independent sometimes. You teach them values and then you have to let them go.
The worst that could happen is that they start boinking and get pregnant.
The best that can happen is nothing.
School dances is when they can socialize, under close supervision.
Teens' main responsibility to society is to study and learn and do well in school.
Until what age are you going to confine and smother your child? Until they are 18, 20, 25?
Several of the Protestant kids in the neighborhood that did NOT have such adequate parenting ended up pregnant. Some of them got abortions while others had the kid.
