You run into an exact copy of yourself, what would you do? He/she could be you from the past, you from the future, you from an alternate universe, or just someone in the mirror who happens to do the exact same thing as you do at the exact same time.
I met myself once. He wouldn't speak until spoken to. And even then, he would talk about nothing other than his own opinions, or something about ska music. He also wouldn't take off his damn headphones, and he would not look away from his cellphone. In other words, he's a giant jerk, and I dread having to see him again.
