Visitors to Britain are often surprised to find that the weather is an almost endless topic of conversation.This is not, as some people think, because the British are not bright enough to think of anything else to talk about, but because there is always a feature of surprise in the British climate.In England, we never know from one day to the next what is in store for us.One year, we had a period of very hot weather in early June and decided to spend the weekend at the seaside.I packed the bags and got the children ready to leave.When at last everything was in the car, I sat down in the front seat, hot and tired, and gradually felt relaxed in the cool wind as my husband drove towards the coast.For the first few mile I thought happily of sea and send and peace.But not for long, the sky began to cloud over and by the time we arrived it was dark grey.We cooked supper and put the children to bed, hoping that the sun would shine next day.Saturday was wet with a cold wind which reminded us sharply of winter, but we put on ourraincoats and drove to the beach.It was wide, empty sand.We were not so brave; we went backTo our little holiday house and sat round the fire playing indoor games.The following day was sillwet and unfriendly and we were glad to go back to the comfort of home.
