1. I saw Sue in town yesterday but she didn't see me. She was looking the other way.
2. I met Tom and Ann at the airport a few weeks ago. Theywere going to Berlin and I was going to Madrid. We had a chat while we were waiting for our flights.
3. I was cycling home yesterday when suddenly a man stepped out into the road in front of me. I was going quite fast but luckily I managed to stop in time and didn't hit him.
