see Paul Graham's essay on See Randomness, (http://paulgraham.com/randomness.html) it might or might not be true for your case but personally it makes me feel better when I am in similar situations by maybe seeing things in better perspective. A lot of times when I am confused about someone's actions toward me I tend to think that it must be about me and to make it worse I exaggerate it in my mind. Sometimes it isn't rational to always expect a rational response from other humans. We are all humans after all, and we make mistakes just like everyone else, a little understanding goes a long way.
