When you are a teen, don’t agree to go out with a boy that your best friend likes. Even if he does not share her affection and even if you have never had a boyfriend before and you are completely overwhelmed by the fact that a guy… any guy would like you over her. Just don’t do it, because chances are that the guy will totally not be worth it and you will wish that he would just leave and that you could have your best friend back again. IF you are lucky, maybe… maybe… she will agree to be your friend again but things will never be quite the same and sometime later like when your thirty-something you might be in the shower and you might think of that time and know that even though ultimately the friendship survived; you cut off a branch of that relationship that never quite grew back. And that might make you sad.
