Do you feel that some people are too perfect for thier own good? For instance, they have become judgemental and self righteous. In the Bible, Jesus condemned the Pharisees for such an attitude as well as for legalism. Has anyone confronted someone they felt was holier than thou?
Note, holier than thou people typically try to brush off their criticism as advice. Many of them are parents, but they try to parent adults of a sound mind. 8-| Of course, that's not saying that some advice is helpful, like for instance, telling someone to take a bath.
