I would have to say the revealing clothing that the girls wear today and the sloppy look of the guys. None of that would be acceptable when I was a teen.
What is something teens do today that was totally unacceptable in your time?
Too much sitting! When we were young, we had to get up and walk to change the TV station!
Nude selfies ... When I was a teen I pushed the boundaries by always wearing crop tops .. OMG my belly button was showing ! :) I really want girls to know that once they send a pic through text or snap chat they can never get it back. It's out there forever. Even if you send it through snap and it's only for ten seconds .. Screen shots girls! Smarten up and have some self respect .. But belly buttons are cute , just sayin :p
