16 yr old dd does errands on request, but I don't insist if she is genuinely busy with something important, as she's an A Level student now, and has people to see, places to be...
I feel that it's more important to teach her independence and self-sufficiency, so although I don't often ask her to wash up or clean the bathroom etc, she has done her own laundry and ironing for a couple of years now, is responsible for her own room (which is a hovel, but that's beside the point: I don't have to deal with it), and she organises herself in terms of transport to activities, academic work etc. She also cooks her own meals, as the vegetarian of the house, and sometimes prepares stuff for her younger sister.
She is going away with the school tomorrow, and has organised her own packing, passport, buying of toiletries, snacks for the coach etc.
As I'm not out of the home working at the moment, I expect to pick up a lot of communal stuff, but she adds very little to the general load, IYSWIM, as she is pretty good at looking after herself. It might sound a bit 'detached', but I think she is fairly well-prepared for going to uni or whatever in a couple of years.
