As weird as it sounds, it's true. My eyes change colors depending upon my mood: When angry, they turn gray. When I'm happy, they're bright blue. Sleepy they turn green. It's the weirdest damned thing ever, and I'd noticed it for a while, but never really said anything about it until my girlfriend commented on it one day.
I like it, though. It's kind of fun - to have colorchanging eyes.
