Lord help me for this, I know I'm in for a flaming and I AM old but....
The more I see of them the more I can't stand them. They are (and I generalise here) rude, swear in public places as a matter of making conversation, the girls are plastered in makeup with over processed hair, they Twitter about how hard life is cause they have to get out of bed and go to school, they do nothing around the house, think everyone owes them, feel allowances should be made for nasty behaviour because they're teenagers (??). Push past you in the street and then say "WELL EXCUSE MEEEE" like you did something wrong. One I know well, talks with friends about anyone they don't like being like "a special needs kid" and "mong".
Oh God. Rant over. I just don't like them. And I'm about to have one of my own next year!
