This is so difficult. It's not what you might call, polite conversation.
I was trying to explain to a doctor, what had happened to a young lady whose right tib & fib were fractured in a riding fall. Unfortunately, said doctor had a humungous cabbage leaf hanging from his nose. Well I can't think of a less way of saying he needed a good blow. (That's not the sort of blow that you smoke Heather,)
So how do you tell someone? Or do you simply ignore it? I would want to know, would you?
