(get your mind out of the gutter -- this is a family blog. except for my kids -- you're about to understand why)
Have you ever thrown away trash that you knew was valuable trash to a shorter member of your family, then when they searched for it you tried to offer helpful advice: "Did you look under your bed?" "Is it in your brother/sister's room?" "Did you maybe accidentally throw it away?"
You've never done that? Oh, well, me neither, then.
