One is never lacking in opportunities each day to be happy,
as the wonderful G.K. Chesterton reminded us in 1908:
The test of all happiness is gratitude.
Children are grateful when Santa Claus puts in their stockings gifts of toys or sweets.
Could I not be grateful to Santa Claus when he puts in my stockings the gift of two miraculous legs?

I became instantly grateful when I saw this photo. I recalled in a flash when the size of my girls feet matched that of the baby in the picture. I recalled the smell of my girls as babies. The tears both joyous and heartbreaking. I am grateful that they chose me, I am blessed indeed. -W38
