I used to live in an industrial town (in northern England), which was twinned with an industrial town in northern Germany, certainly no holiday destinations, neither of them! My wife and I joined the twinning association, because we were interested in how ordinary people lived their lives, and the Germans were similarly interested in us. We would organise a group and go over there by coach, and stay in the German members' homes once a year. The following year the German group came over here and stayed with us. The original arrangement was started simply on a "would like to get to know you" basis, and "councillors' junket" it was certainly not, although I have heard of towns in which the twinning arrangements are conducted on a strictly civic level. My wife and I are not now involved with twinning, but we have maintained contact with the friends that we made in Germany. I can recommend it as a way of seeing how people in another country live.
