THE THIEF

He came in one night. Before I knew what happened he only wanted my heart. He was smooth certain he had done that many times before. He returned and left a secret surprise that I do not believe that it is to be revealed. He's sneaky, quick, loving he is the BEST THIEF IN THE WORLD. I know he has mastered his skill. What number am I? I said even somethings I really don't need to know.
