The Salvation Army, Goodwill, Deseret Industries, Secret Santa, Angel Tree, Toys for Tots, and so many more. All of them organizations that help people who are down on their luck and all of them organizations that either only work around Christmas, or do their best around Christmas.
I know it causes a lot more stress for a lot of people. Both on the giving and receiving end of the charity, but I think it's worth it. Even in parents have made horrible choices, we all think that their children should have Christmas because they didn't make the choices. Anyway, Christmas Charity is my number five.
