The midnight stalker; Izzy is killing us.  Middle of the night, wandering around the house, putting all the lights on downstairs, trying to get into bed and waking us all up.  This is what happens when she has a few days sleeping with somebody else.  We end up with Joey coming in to us at 0200, indignant, to tell us that Izzy has woken the boys up.  And they need their sleep.
