My friends call me Ad, because they're too lazy to say Adam, and everyone else calls me Gow, which is annoying because I have an identical twin brother, so we never quite know who people are calling for sure. I call my twin several variations of Daniel, but not Daniel, I call him Dan, Danny, Danny-Boy, Dan-Dan-Danny, Dandini, Dan-Dan-the-dandy-man, Danathor, etc, all of which really, really piss him off, but I'm bigger than him, so I get away with it.
