How do your friends influence your children?

Are your friends a good influence on your children? Or, do they swear, smoke, drink excessively, or talk about adult things in front of your kids? There is no suggestion here to change friends, however, perhaps you ask them to tone down their conversations when the kids are around. Alternatively, you could change the times when your friends are around to avoid some of their contact with your kids. Children will be exposed to all of these things enough in their young lives without it being in their home too often as well.
