I have, from time to time, had overseas students come to stay with us and study English one to one or one to two and they have had to be students who were 18 plus because I couldn't take the responsibility for younger ones. But I, with my love of teaching and young people, have thoroughly enjoyed doing this. I may do it again from time to time. We live in one of the most beautiful areas of Britain with some truly lovely towns and cities nearby and it is an ideal holiday/study area. Has anyone else done this?
