one of the many things that helped me along the way was something I fought believe me when I say this. The thing that bothers us the most about someone is something we don't like about ourselves inside. other wise it wouldn't incite us. Those are the parts that make us confused as to what we want to do. some people in life we learn to stay away from, others we learn to just feel sorry for. It's the one's that use that to hurt us or others that I really walk away from. Don't worry, the words come out that you need to read yourself. LadyJ

Throughout life we all meet people that, well...basically make us want to strangle them but we don't. The fact that you recognize your animosity (dislike) for her means you have a more superior knowledge of people than most and will probably learn to accept or at the very least avoid her. Either way you captured something real and true in this one.

it will be okay, and your ability to use that self control shows a lot of growing up!
