Most people live extremely busy lives. Up early, get the kids ready for school, Make Breakfast and packed lunches, clear up, dash out to get the kids to school, leave for work, have a full day, work late or brave the rush hour (one of you has to get the kids from school, or be home in time to supervise their homework and see they don't cause too much mayhem).
Home at last! Time to have a quick cup of tea before giving the kids some attention, eating supper, clearing up, putting them to bed and, at last, a chance to sit down and chat to your partner, watch a bit of TV and kick back. The chances are you fall asleep right there and have to drag yourself up to go to bed.
