Definitely an extrovert. Not long ago, Mr Moo and I were standing in line at a store and I started up a conversation with the people standing in line behind us, then included the cashier when it was out turn at the register. Mr Moo asked me later if there was anyone in the world I wouldn't talk to given the chance. Heh. I like getting to know new people and it doesn't cost anything to be friendly, so my answer probably would be 'no'.
