DD's 12 & 15 don't have many chores, but they both have to take it in turns to pick up dog poo in the garden twice a day.
After they'd both left this morning, went out and obviously had not been done for at least 24 hours and ... what had been picked up was not done properly.
We've warned them repeatedly, so when I paid their pocket money for the month today into their bank accounts, I docked them £1 each.
