I think that is the cutest little letter to Santa. Never mind little one that you never wrote Santa before, but you wanted to thank him for spreading happiness all of the world. Keep your good thoughts. When someone so precious as a little child has this kind of thank you in mind, it makes the grown-ups look like idiots. Never stop a child’s dreams of joy and happiness, or someday he/she will have other dreams that you will wish he/she never had.
