Amy is engaged to Martin but still loves Barry. She writes Martin a letter breaking their engagement, then realizes Barry is a faker. Amy can’t retrieve the letter but Martin doesn’t mention it and they are married. When they return from their honeymoon, Martin discovers the letter and Amy begs him not to open it. Martin is suspicious but burns the letter because the stamp was upside down, which means “I love you,” and he feels Amy must have done this subconsciously.
