Happy Birthday

During Xmas I sent a letter to my old friend Matt. I had gotten his address from Kaivan, our mutal friend. Several months after having sent the letter, it was returned to me. I asked Kaivan if Matt had moved. Kaivan in turn asked Matt about his address. Matt confirmed that there was a problem with his address. Kaivan relayed this information to me. He did so by taking a screenshot of a conversation he had had with Matt over text message. 

A few days after Kaivan sent me the screenshot, I looked at it again.  At the bottom of it, I saw that there was one last message from Matt, one I hadn't seen the first time I looked at the screenshot. Matt had written this: "Yo, if you speak to Chad, wish him a happy birthday."
