Not usually, I don't particularly like people. Most are unreliable and dishonest. On the other hand, when I am a good amount tipsy, I turn into a social butterfly. I think this is due to lack of any real emotional investment accompanied by the fact that drunk people will laugh at jokes at their own expense without realizing it which I find to be very amusing.
I like to think of myself as a good person, not a nice one.
I think I tease everyone a bit whether or not I've been drinking. I used to be pretty mean all the time involving social interactions, but I never thought it was unmerited. Friends are kind of like your garden, you have to weed out the bad ones, and if someone cannot laugh at their own expense they're usually not worth having around for one reason or another.
