This is for the younger women (add late teens too) and for the younger men out there. Ladies: Never assume you can "change him". If he needs to be "changed" let him do it. If he's too damn stupid or lazy to do it on his own: DUMP HIM! Seriously, he's not worth the emotional tornado he'll put you through.
Guys: Seriously, if you're like this idiot and you did that to my daughter, I would ensure you wouldn't be able to have kids to procreate another generation of stupidity. Then again, my daughter is too damn smart to date anyone as stupid as this guy. He really needs his arse kicked, more than once.
