My daughter has an imaginary friend. Her name is Tibby. Tibby can be a baby, she can be a mummy. Tibby has had a full life, I can tell you that. She flies on planes, she goes to England, she plays at the beach and she doesn't like having naps during the day. Tibby is mentioned many, many times each day. She's a character, that Tibby. My daughter, too.
