IamA Mirror twin, AMA.
I have an identical twin brother, we were born mirror twins. That means we are essentially exact opposites, he was born left-handed, deaf in his left ear, and parting his hair to the left, I was born right-handed, deaf in my right ear, and parting my hair to the right. I get asked questions about it all the time, so I figured I may as well do this!
EDIT: Here's a photo, I'm on the far left, my brother's on the far right. We're 16, so I was a little hesitant to post a picture, but whatever. http://imgur.com/asRKlun
