My OH and one of our lodgers reckon they can't fall asleep without putting the tv on first. I couldn't do that, the rise and fall in pitch and volume would drive me mad, if the flashes across the room didn't.
I think it's a waste of electricity. My OH often falls asleep on the sofa as I will not have a tv in our bedroom. I get cross when he's lying there drooling as I'm trying to find a spot to sit down and feed our baby at 5am.
Who else needs noise to sleep? Why??
