There have been many, but the one that stands out happened a couple of years ago when my daughter chose the name of little girl and boy off a wishing tree. They had a single Mom that was having a very difficult time.Their wish list included a few simple items items such as a toy, a doll,and some clothes. I don't remember the wording in the letter, but it touched my daughter deeply. On the evening she went shopping, I came home to find our living room full, I mean full, to the point you could hardly navigate through the piles of toys, clothes, and goodies.
When I asked her about it, she smiled and said, "they need Christmas more than us."
The best Christmas gift I received that year was not that she didn't give me a gift but the look in her eye and the smile on her face as she left to deliver the gifts to organization for someone she didn't know and would never meet.
