Shouldn't think a contestant on a TV programme will ever be privy to your comments to your wife. It's human nature to notice and comment on things, including appearance. If I go to town, I spend the whole time mentally tutting to myself about the sights I see. It's when you say these things to the person or someone who could pass it on is when it becomes unpleasant. My father in law is quite posh and he says that a gentleman never intentionally insults someone (doesn't mean he doesn't have mean thoughts though).
