18 hour power cuts are the norm at the moment, I think Zack forgets that power exists sometimes, it is off by the time he wakes up in the morning, and only returns around 10pm - long after he has gone to sleep... something he has recently started, when the power does come on... he looks around with an absolute look of delight (often runs for the TV to turn the teletubbies/winnie the pooh video on) and says in a voice of absolute wonderment.... POWER!!!!
