I hate the saying I love you to the moon and back.
Really? I associate it with this very sweet tender kid's book: Guess How Much I Love You, to ultimately describe to a child how much a parent loves him. My kids liked the story a lot, but I thought that description still conveyed a limit, so I started telling them "I love you to the end of a circle".
Me, Type A? Maybe - I'm not done analyzing it yet.
