I've been able to stay out of gossip and drama through high school and college, so I guess I'm not that talkative.
But I can be loud, especially if my sense of humor takes over. For the record, I have nearly no filter on my humor, I've found. I recall this one time, at work (a retail store), I was walking around the department, while my manager (the nicest gay guy you could ever meet) was ringing up a decent line of customers. Well, I found a plastic spoon on the floor, and without really thinking, I held it up and said loudly, "Hey Scott! Wanna spoon?" and just started laughing.
I also told the store boss (when he was telling me to do something and was stammering a bit with his words), I said, "Easy for you to say!"
I'm rather unconventional in the work field, but I've never gotten in trouble... yet. ;)
