Does a nasty disposition count ?
How about a nice disposition?
Conflict: It doesn't have to happen.
As a general rule, I believe in treating people as well as I can. I have a very active sense of humor, and I enjoy making people laugh. I am pretty easy to get along with, and my job is such that I work regularly with everyone from elderly ladies to hardcore gang-bangers (emphasis on gang bangers). In fact, normally I am pretty non-aggressive. I don't particularly enjoy conflict, and so I try to stay away from it.
On the other hand, I can very easily become the nastiest, meanest, most unlikable character you could imagine. Just a horrible, ultra-confrontational, jerk of a human being. It happens rarely and though when it does I flip to that personality on purpose, it isn't an act. I am pretty laid back, but I am not about to get walked over or victimized. I mean, I was a pretty good Marine once, and we aren't knowen for our delicacy and sense of decorum.
Frankly, both have their places. In my own life history, I have been able to talk my way out of far more sticky situations than I have fighting my way out of them. But, when it is time to get serious, it is time to get serious. I would totally rather not fight, but if I can't talk my way out of it, then I will try and talk my way in to it.
