Last Sunday was definitely not a good day for me. It all started when I got into my car and it refused to start. I immediately realised that I had left the lights on and the battery had gone flat. I telephoned my friend George and he came round and helped me start the car. I then drove into town to see a friend. I had arranged to meet him at six thirty, but by the time I got there, it was ten past seven and my friend was not there. I waited for him for an hour despite the freezing weather, but...

Last Sunday was definitely not a good day for me. It all started when I got into my car and it refused to start. I immediately realised that I had left the lights on and the battery had gone flat. I telephoned my friend George and he came round and helped me start the car. I then drove into town to see a friend. I had arranged to meet him at six thirty, but by the time I got there, it was ten past seven and my friend was not there. I waited for him for an hour despite the freezing weather, but he didn’t come. When I returned to my car, I saw that someone had broken into it, probably looking for the radio. Luckily , I never leave the radio in the car ! There was nothing I could do but get into my car and drive home. Later I spoke with my friend and discovered that he had waited for only half an hour and left. He didn’t even apologise for not waiting for me longer.
