Yep.. its hard to watch someone flirt with something you know from experience is dangerous, because there's nothing you can do to convince them sometimes. You run more of a risk of causing them to want to prove you wrong, and to want to even more aggressively pursue the thing you're warning them about. Haha... thought of something silly, in Knocked Up... the little girl with curly hair? Her dad says to her, Don't do what they did. Of course her response is "I'm gonna do it!" Typical!
