For our anniversary he gave me a gift. Before he gave it to me he told me a clue: It is living, and it is a pair of hearts. I tried for a whole day to figure it out and absolutely could not. Everything from "Black market hearts?" to "Bleeding heart flowers?". Then I walked into his room and saw them and the clues made absolute sense and I loved them. But it drove me nuts for a day so now I am returning the favor.
Go on. Guess.
