Am I the only one who feels this way?

I like to think that I am really nice person. I also like to believe in the human spirit, that love will conquer all. I also think that it is important to forgive everyone, to understand that everyone is imperfect and that God loves all of His children. However, I have days where I think what kind of idiot are you? Do people really not realize that their actions effect people. That their choices can hurt others, for all long time.  There are days that I just want to say, "Yeah, I'll pray for you..."
