my father is a Santa Claus

A long time ago, my father took me a toys' shop and said "Which toy do you want?" I was very happy and answerd. But my father didn't buy the toy then. A few days later, christmas has come. I woke up and noticed something at the bedside. I opend the package. There was a toy that I said "I want this" to my father. I thought my father is Santa Claus.
