An adage that broadly states: "One will remember what is needed only after they are out the door." The name Theodore is pun-based, on the fact that is nearly homophonous with "The door". Also known as "O. Theodore's Law", as in, "Out the door". Also can be stated as, "If there is something that can be forgotten in packing, it will be forgotten.", though the term is more related to day items.
