How far do you go in disciplining the children of your friends when they are not there and you're watching them? Are you more lenient than with your own children, or do you expect them to tow the same lines?

If your friends are present and their children aren't behaving... do you leave it up to them to dicipline their child/ren or would you say/do something to correct their behavior?

How do you feel if someone else took it upon themselves (whether you're there or not) to correct your child/ren's behavior?
