Confusion may sometimes arise when two words are either spaced apart or the same two words used together as one word, e.g. "pull over" or "pullover". There was the case of a police officer driving up the M1 when he noticed that a car ahead was meandering in and out of lanes. The police car drove up alongside and the officer was amazed to see a lady-driver knitting as she was driving. The officer drew down his window and shouted out "Pull Over"! The lady driver, whose window was already down, shouted back, "No luv, it's not going to be a pullover, I'm knitting some socks for me 'usband" Dave.
