After two or three minutes the students began laughing and laughing! Why? Suddenly I looked down and understood. I had put on one black shoe and one brown shoe!

Henry: After seeing a film, we decided to walk along the street. The street was very busy and we started holding hands. Suddenly my wife saw a dress that she liked in a shop window, and stopped.

James: I had decided to buy a new house, and I'd made an appointment (约定)to see our bank manager. I'd never met him before. I was lucky enough to find a parking space outside the bank.
