I laugh at almost anything, it could be a weird situation, like I think its funny because I know exactly what they are talking about, but the other person doesn't. Or it could remind me of something funny. I am famous for laughing out loud, at moments that aren't really a good time for laughing, like when your getting yelled at by a teacher, and they're yelling while giving you a speech. I always laugh during those, I can't help myself.
