They're all... looking... a little... nervous right now
The best advice I've heard was from a lady in her 80s at my grandmother's 90th birthday. I was telling her how wonderful my children are. She said, "Don't forget your husband: you only borrow your children; your husband you'll have for ever."
I knew it was really, really popular when my granny told me she watched it, and was addicted. When your granny is interested, you know you're on to a winner.
