My husband and I are very fortunate to just get whatever we want at any time, so we decided not to buy each other Christmas gifts.
Last year, after Christmas, I bought myself a Christmas gift for many years to come--the Viking Diamond sewing machine. That will do for many Christmases; I do manage to buy fabric whenever I want it. (This will probably be the last sewing machine I will ever buy.)
At Christmas time, we send checks to various charities, along with the gift bags of groceries from the local market.
As for the grandmother with the sick little granddaughter, I am so happy for you that you had a good day with your granddaughter. Maybe Santa will bring her the gift of good health so she can live the life of a happy, healthy five-year old. God Bless you; I know your heart must be hurting.
