That's good to me. I don't either. It is VERY rare that someone brings a child to my house. I have a MEAN cat that HATES children and has attacked everyone that's ever been in my house. I tell them to bring their children at their own risk, but that my cat will not be locked away to please their heathens.
Smoking....I smoke, so I let people smoke if we are having a party. Other than that, we normally smoke outside.
