I guess a troglodyte, and I guess I was a Cleric. I'd like to say I don't remember because it was 15 years ago and I was still in elementary school, but it's actually because D&D was not my first roleplaying experience. My first exposure to roleplaying was through Shadowrun, and I do vividly remember my first game and first kill in that game, a thug on a fire escape who was part of a gang hitting up our characters for money.
Four of us played in a booth at a McDonalds, using convenient props to represent the alley where the combat took place and white pipped dice to represent the players. It was difficult to keep the fire escape thug on a level above the rest of us, the Shadowrun book kept getting passed around the table because everyone wanted a look at it, and the slightest brush would take the die off its perch, so I killed him to make things easier. With an Ares Predator.
Some ten years later I was confronted in an art class by someone who remembered me from that day in McDonalds, and questioned me about what we had been doing hiding behind chicken nugget boxes and talking about shooting people. I tried to explain about roleplaying games, but he was only interested in ousting me as a lunatic, and it was all pretty awkward.
