I wouldn't do it personally... but I can understand how after spending your holidays with certain people for 20 years would be a hard thing to let go. So I agree with bebob...Send the cards, that's the only way to find out. But I think doing this every year could end up being depressing. You can't grow if you're still dwelling in the past.

I disliked visiting my inlaws. They lived out of state and so visiting was a big deal. I am so grateful I'm not obligated to be stressed out and criticized for weeks until the holidays are over. Because I have a child with my ex, I still have to see them but only in passing and that's more than enough for me.
