Dear Sir
I was in your store on Saturday with my four year old son, Owen, and I took him to visit Santa at his grotto. He was in for longer than the other children. Afterwards, I asked him what he had asked Santa for and he told me he asked for a bike.
This is the first my son has spoken since he was born and it has absolutely made my year. I would like you to pass on this letter to Santa to thank him for his kindness and patience.
With my warmest regards
