Clandestine, you're totally right with some of your comments and you're really mature beyond your years. I think you said once that you're 20 or 21 and you're a hell of a lot more mature than lots of my peers (I'm 34). You're absolutely right that it absolutely wrong for people to make fun of hair loss and then chalk it up to being drunk. Being drunk is simply no excuse to act like a f*ck-stick and then apologize for it later.
If it's any encouragement to you, I just heard from a friend who started losing his hair in high school. He's married to a hot-as-hell chick and just got back from a vacation literally around the world. He's one of the most secure people that I know and I met him through my old boxing gym. He doesn't even want to talk to me about hair loss because he can't believe that I'm making such a big deal about it. I wish I could be as secure as he is, but it's been very hard for me. But you're much younger than I am, and you seem to be very secure for your age.
