Act your age not your shoe size.

My oldest nephew, the one who coined "Aunt CindyLand", will be 15 soon. Really. He'll be 15. (Funny, I don't look old enough to have a 15 year old nephew).  He's 6 feet tall & wears a size 14 shoe.  My sister is sad because she can't use the phrase "Act your age, not your shoe size".  Luckily, she has a 13 year old son who is only in a size 9.
