What lack of sleep can do to your houshold-expenses.

I got to bed late last night, beeing very tired and having quite a headache. When I woke up this morning, I found out that the heating in the living room has been working on highest level throughout the whole night, the dish washer was still on, the light in the bathroom hadn't beend switched off and, as my favourite, the radio was still playing. Hm. No, I was not drunk. Looking forward to my heating bill.
