Someone stole our Sweethearts!

The other day I purchased Sweethearts for my class. They had been great so I thought that they deserved a treat. However, when we returned from guidance we noticed that the Sweethearts had been stolen. To help us find who took the Sweethearts, we placed wanted posters in the hallway to inform others about the theft. Thankfully they were returned today so we can enjoy our treat. We still wonder where they have been this whole time...
