Christmas Cards

I have noticed that there is a trend for people to send Christmas cards and instead of a family photo, you get pictures of their kids. I have to wonder why they would not include a picture of themselves(the parents)?
I know some people may not want others to see themselves going bald, obese, pregnant, etc......so what. If you see my mug on a picture, then it can't get any worse than that, plus I hate having my picture taken.
A lot of blogs don't include pictures of the parents, but that doesn't bother me as much because usually people don't mail me a blog.
Maybe in the future people will just include a picture that is such an extreme close up that all you see is an eye or a hand.
