Is your moon in Aquarius? Diox?
If your sun sign is not Aries, then it's gotta be Sagittarius if I am to have any confidence in Astrology.
If I am still wrong, then you are Leo, assuming astrology has validity.

I never really cared too much about Astrology, but my girlfriend is really good at it, and she is more social than me.
She could guess your sign in a heartbeat. I have seen her do it more than once.
