Short, sad and sweet. This could be quite good with the right musical arrangement. The only line I have trouble with (and it's a very small thing) is: "For the address has changed". Up to that point, and throughout, your lyric has a very real and conversational feel. Just my opinion, but I would drop the "for" at the beginning of the line. If you are trying to create a moment that sounds genuine, I'm not sure how many people would actually speak that way. Over all, for a short piece, I think you struck a nerve and a sentiment that is very relatable. Best of luck.
