If there's one thing I can say about my parents, in retrospect, it's that they were excellent about not playing favorites. (Actually there are lots of things I can say about them, and most of them are good, but I've got to narrow it down in the confines of this little blog.) My sister might contend that I didn't notice because I was the favorite, but I would argue that. Granted, there were only two of us, so it might have been easier to divvy up the love, but I don't think that was it. If a parent is going to show favorites, it seems that it would be more likely to happen if your kids are very different from each other, and you relate to one more than the other.
