In the year 2000 at Christmas we had a long holiday because Christmas was on Sunday. The roads were busy and we had to wait in a queue. We drove to the end of the street and parked on the side of the road by the corner. We went into a pub for our Christmas dinner. There was lots of food on the table. We knew that in a few minutes time we would sit on a chair and start eating.
