Just something I have pondered for a long time......

I am a strange person who by most accounts could very well be classified as a jerk or an ass or whatever term you would like to use, but somehow when I make fun of people many people tend to like me more. I am a very caring person when it is needed, but mocking people and making fun of them is just something I do for some messed up reason. I think it has to do with sibling rivalry and my upbringing but that is beside the point. I think that the way things tend to work out in the respect is just so weird. I really just want people to comment on this so please comment on this and give me your thoughts. I guess this sounds very conceited. It is just an observation that I have made through time. Can someone give me a good explanation please? I was also just told that I can be a complete jerk one minute and then the sweetest guy the next, that is kinda weird too.
