I had a cousin who acted like she was still 6 years old when she was 15 because she thought being all innocent and goofy acting would get her more presents from "Santa".
Then as an adult she stole everything that she could from a couple of estates in which she was supposed to be sharing the money and antiques, now after all these years she has found herself "alone" with no family!
Go figure?
Adults are just taller, heavier children, many times.
