I'm not a liar at all, and never have been. Outside, of course, of the white lies sorts... you know, saying, "oh, yes, that's very nice", when in fact I don't think so and those of being evasive of how bad things really are. But I never make stuff up. It never even occurs to me to do so. Beside is just being my personality, I think there are a couple of factors that are re-inforcing... I have a big (verging on paranoid) fear of "getting in trouble". It's not unusual for me to fear it even if I haven't done anything wrong. (Thank you, childhood.). Also, I have a hard enough time keeping reality straight, and could never possibly keep "stories" straight.

I'm freakishly trustworthy. Sometimes, I have trouble in the "real world" because I don't "get it". The games, the deceptions. I have to really work at following, say, a story of palace intrigue.
