A caring sort of anger

I realized something very strange the other day. I can only become angry with people I care about. Yelling, arguing, and just being an ass are really things I can only do if I care. If I don't care about you I figure "it isn't worth it", but if I do care I will argue until I am blue in the face. So if I've ever gotten really angry with you, there is a decent chance that you're someone I care about.
