What tasks do they now perform?
Before last person leaves the house, she checks to make sure the house is ready to be unoccupied. Specifics vary by family and person, but she will typically check doors, windows, lights or appliances to make sure they are all locked or off. Another task performed is checking whether or not a child has gone to sleep yet. This requires a parent to go to outside the child s bedroom and check if the lights, computer and TV are off. The idea is that a child will most likely be asleep if all lights and electronics are off at night because there is nothing to keep him awake.
What tasks are desired?
