When my daughter was a teenager, our house was informally the "youth club". We could get back from shopping and find anything from ten to twenty young people sprawled around the sitting room. Every now and again it turned into what was known as a "bopping night" when we played my eclectic, not to say eccentric collection of records and everyone danced until they dropped, then had a sleepover. The young people were allowed to help themselves to soft drinks, crisps and biscuits, but were not allowed to touch alcohol. They were not allowed to smoke or bring drugs into the house and they had to let their parents know where they were. There was hardly ever a problem – someone used the phone to call a sex talk line which ran up a bill of over £200 (it's routed via Suvalu) , but the young people policed that themselves and it never happened again, and when there were sleepovers no one was late for school the next day. We dispensed plates of burgers and chips from time to time, comforted young people in trouble and despair, helped with homework and exam revision and we also had loads of fun. They truly were unexpected visitors as I never had the slightest idea who would be there and there was always someone new every week. I remember walking into my kitchen and a young man I had never seen before asked who I was. It was a safe, but relaxed environment for young people and they were both appreciative and affectionate. (I don't suppose you could do that in these days of political correctness without a police visit.) I really rather miss the "youth club", but, of course, they all grew up.
