I drink. Quite  a bit. If my parents ever found out, they'd be pissed off.
My masturbation habits. I they ever found out about that, I don't know what I'd do. I know it would be quite awkward, though.
Also, the fact that I'm atheist. I saw how my parents reacted when my sister told them that she didn't believe in god. I decided it's just better to keep it a secret, rather than go through that.
