Dealing with disrespect.

One thing I know I don't handle well:  disrespect.  I don't even know why this person is disrespectful to me.  Either it's a character flaw on their part or they don't like me.  Either way, I don't tolerate that kind of crap in my AOR.  It's easy for my anger to get the better of me in a situation like this, but I am not going to let it take control and ruin any chance I have of fixing this in a constructive way.  I had to catch myself today to keep the anger from coming out and I think it flashed across my face for just one second.  I didn't respond to the disrespectful behavior in words, but I think that my facial expression for that split second paired with my change in body language got the message across that I am not someone to be trifled with.  I just don't want people to be scared of me.  I have a large, intimidating frame to begin with and it's hard enough to break down the barriers of wariness that I get from others on a regular basis.  I do eventually succeed, but many people's initial reaction to my presence when they meet me is fear.  They hide it well, but their body language tells a different story.  I hate it, but I can't change that aspect of who I am.  I just have to learn how to disarm people better.
