Another question I have on this subject is how to behave when people around us are uncivil. I don't mean our children, of course. I mean people over whom we have no authority, and therefore no right to correct - for example, strangers who ask us directions, or neighbors, or other people's children when they're not in our homes.
I guess that as long as they're only being uncivil and not sinning, and they're not close enough to us that we'd have a right or duty to correct them, then it's best not to let it show that we're offended. But I have the idea in my head that if I don't show offense, I'm showing approval of their behavior. I have a huge problem with this.
