My sister Alice and I sat down in front of the fire and wrote a 1 to Father Christmas, telling him about all the presents we 2 . We carefully posted the letter to "Father Christmas, the North pole"… Christmas Eve came, The whole family helped to 3 the house, put up the Christmas tree and blow up the balloons. Then, in the afternoon, when Aunt Kate and my two cousins arrived, 4 was ready. Before we went to bed, we left some wine and meat for Father Christmas and then put our 5 at the end of our beds. We tried to keep 6 as long as possible to see Father Christmas, but the next thing we knew it was 7 Christmas morning! We couldn't wait to 8 the stocking. It was now full of all kinds of small present and sweets. Christmas morning was bright and sunny. After going to church, my cousin David and I went out into the garden to 9 our new present.
