【明報專訊】Mrs Wilson was giving Chan Wai Lung, her homestay student, breakfast. Wai Lung was from China and learning English in the UK. Wai Lung still looked sleepy, and said little. "Wai Lung, I'm sorry. I forgot to buy your favourite breakfast cereal. Is toast OK?" she asked Wai Lung. Wai Lung said he would eat toast, but looked a little unhappy about it. Mrs Wilson toasted two pieces of bread, then put them in a toast rack on the table. Wai Lung took one piece, put on butter and jam, and ate it. Then he took the other piece of toast. He put it on his plate, and he looked at it for a long time. Then he took it in his hand and studied it carefully.
