Christmas tree decorations

I like looking at the Christmas cards & letters that I was sent this year. They are all posted on the bulletin board in my study. There are the ones from family w/ pictures and the ones from friends to catch up on news. There is one from the Auto Collision Center - never a good sign when the local car repair shop considers you a good customer. Then there is the obligatory card from someone I don't know. There is no return address, though they did sign it. Wish I could remember who they are!
