I Like the Parents, but Hate the Kid

Does the apple fall not far from the tree, or does it not? More tales from child care. There are several kids that I really do not like. They are mean-spirited, selfish and clique-ish. How does a four-year old get like that?

Some parents, I see, are like that, so I can understand, but these parents are really cool and I like them. So what happened to the kids? Where are they learning such behavior?

Are the parents really not that cool? But they are better at masking their dark sides?
