The second main reason [that Christopher finds people confusing] is that people often talk using metaphors. These are examples of metaphorsI laughed my socks off.He was the apple of her eye.They had a skeleton in the cupboard.We had a real pig of a day.The dog was stone dead.The word metaphor means carrying something form one place to another, and it comes from the Greek words . . . .I think it should be called a lie because a pig is not like a day and people do not have skeletons in the cupboards. And when I try and make a picture of the phrase in my head it just confuses me.
