i have never really had a nickname :(
one time a guy was calling me Kam for a while, and then i realized taht it was because he thought my name was Cameron
he called me Cameron once and i was really confused but I just let it go, let him call me Cam i guess for a while and then one day he's like "why didn't you tell me your name is not Cameron"
man, i was such a geek haha
this guy was annoying though, i didn't wanna tell him just because i just .. didn't wanna talk to him.. he was creepy
