How should I have reacted to this? ?

I personally would have read him the riot act. He's 14 and should know better than to treat someone with such disrespect. He's gotten a good punishment from the girl, he'll be lucky if he doesn't end up in trouble with his school, but he needs to hear from both mom and dad why this isn't appropriate, how it makes women feel to be treated in this way and be ured by him that it would not happen again. I might even dole out my own punishment if I were you to really make this get through to him, maybe a couple weeks w/o cell phone, tv and computer. Disrespecting another person in this manner is absolutely something at this age needs to be firmly abhorred and punished. Too many teens forget the values they were taught and take up the behaviors of those around them, he needs to learn to live his life in the ways that's he's been taught by you regardless of who his friends are or what they're doing.
