Do you have Christmas Card relationships?

I think everyone gets busy especially with kids. If you live far away from someone it is nice to at least get a Christmas card even if you aren't that close of friends anymore. I misplaced a lifelong friend of mine's address and now I no longer receive his Christmas Newsletter that evidently they sent out after receiving all of their Christmas cards each year. I miss reading about how their family is doing. They always wrote the letter in a humorous manner too, which is what I always liked about being around him when we were growing up.
