David and Xiaoyan arrived at the airport in good time. After checking in at the BA (British Airways) desk, they had their boarding passes checked, put their bags through the X-ray machine and went through the passport control on their way to the departure lounge. They didn抰 have anything to eat because they would eat on the plane, but they had a coffee and then they looked round the shops. Xiaoyan bought something for Mary, but David didn抰 buy anything. Then they went to the gate. They had about 20 minutes to wait before embarking. Suddenly David realized that he hadn抰 got his camera with him. They went back and looked everywhere to see where he could have lost it --- in the shops, in the cafe, at the X-ray machine, at the passport control and at the checking-in desk, but nobody had seen it. 揑 must have left it in the cafe,?said David, 揑 should have put it in my bag. I suppose someone must have walked off with it!?
