I could think of lots of things but most of them wouldn't make me very popular! I've grown too old for most of the things I might have done years ago with an invisible coat. I don't want to hear what people are saying about me because the saying "Listeners never hear well of themselves" is unfortunately only too true. I think I would most like to use it to get a bit of peace and quiet! If I were invisible, I could get a rest without someone saying, "Could you just ..." or "Would you mind ...". I could just sit down in a chair and fall asleep without being bothered. Bliss!
