     When friends come to visit us in the evening, they spend their time telling us they are in a hurry and

looking at their watches. It isn't that our friends are all very busy, it is just that we haven't got a television.

People think that we are very strange. "But what do you do in the evening?", they are always asking. The

answer is very simple. Both my wife and I have hobbies. We certainly don’t spend our evenings staring at

the walls. My wife enjoys cooking and painting and often attends evening classes in foreign languages.

This is particularly useful as we often go abroad for our holidays. I collect stamps and I'm always busy

with my collection. Both of us enjoy listening to the music and playing chess together. 

     Sometimes there are power cuts and we have no electricity in the house. This does not worry us, we

just light candles and carry on with what we were doing before. Our friends, however, are lost—no

television! —So they don't know what to do. On such evenings our house is very full—they all come to

us. They all have a good time. Instead of sitting in silence in front of the television, everybody talks and

plays games.
