My suggestion would be to behave and act like as if your young daughter is sitting next to you, your mother is standing behind you, and your pastor on the other side. Anything you can say to them would be OK on NAT. 

 If your family has low morals, then substitute the above persons with your neighbor's.

 You know what I'm getting at so don't weasel out on some loophole.

 Just friendly advice.
