I quite agree with you. My husband and I lived in the middle of a city two years ago. When he stopped working, we moved to a new house in a small village, but costs are higher now. I have to do my shopping in small shops. The food there is more expensive than that in city supermarkets, because it costs more to travel by bus. We also have to pay more for the men who came to mend the TV set or the washing machine, because they have to come further. But it doesn't cost as much to enjoy what is beautiful and quiet in the country. Many people spend a lot of time and money driving into the country to enjoy the simple things of life. Yet we can enjoy them just by going out of the front door. It costs more to live here than it did in the city, but now life is really worth living.(1) The writer is a man.
