People usually give each other gifts at christmas. Mr. And Mrs. William have already bought gifts for their children. They will give them their parcels on christmas morning. Michael and linda have presents for their parents, too. Their eldest brother, david, is working overseas. They have already posted him a christmas card. David will not be at home this year. The others have all bought presents for him, but david's parcels have had to be sent by post. They were sent some weeks ago so that he would have them by christmas day.
