Sharing at Christmas

I'm still in the holiday mood, I guess ...

We all share a lot of things at Christmas: gifts, our time, memories, food ... what is your favorite thing to do at Christmas that has nothing to do with your immediate family? Do you donate to a food shelf? Do you make mittens for troops overseas (yes, I've done that). Do you donate to Toys for Tots or Secret Santa? Do you decorate your office cube and make it a festive spot?

What's the thing you do that is outside your family that makes you feel good about the season?
