I used to have a very independent teenage son, who took himself around the world at the age of 17, paid for by himself, and who later spent 4 months in South America (paid for by his absent mother). Now I have a 21 year old son who drinks me out of milk and tea bags and sugar, but not beer, and who practices incessantly on the piano and his guitar and mouth organ (where did he get that from?), when he is not studying his Uni books. He is polite and helpful, except with regard to the tidiness of his room. He never asks for money, even though he has bought himself a new camera (it's a posh Canon) and is off to Spain for a fortnight next week (intending to live on £5 a day). OK, I suppose I always gave him and his sister the impression they could look elsewhere for support (it was expensive enough bringing them up by myself, with the help of Evil M and Wonderful M).I thought kids were supposed to be a bother. Where the heck have I gone wrong?
