Heres a lovely story I read on Reddit tonight
-"My dad used to do this kind of thing every year. He'd go to our school and ask the people at the front desk if there were any families who were struggling and wouldn't be able to have a nice Christmas (small-ish town, so the school people knew him and were willing to give him some names and information). There were three of us kids, so he'd pick three families. Then we'd go shopping for them. New toys, new clothes, some little things for the parents, and lots of food for Christmas dinner. We'd sneak over to their houses when they were out and leave all the packages in front of the door. Dad would leave a card with a little bit of cash in it and sign it --Santa"
