Firstly, they're teens. Expecting them to give a shit about laundry when they've got so many more exciting discoveries to make (girls, boys, music, films, their mates) will only drive you mad, not them.
Secondly, surely they've got enough on their plates? Why don't you try and shoehorn in learning a language, falling jn love, hours of sport, spot squeezing, whatever, into your own packed week?
Thirdly, what is this MN obsession with making children domestics? Surely it's part of the Having Children Deal that we look after THEM.
Like married, I love cooking and doing the things that make their lives easier. My DH feels the same and does laundry and tidying too; my feminist credentials are safe.
By all means they should know how to look after themselves but surely not sole daily responsible for all the family laundry/washing etc.
Little Victorian drudges!
