Of course, the day I'm working from home is the day that they're tearing off the roof directly above my head. My back just squicks every time they remove a nail - sort of like the sound of fingernails on a blackboard.
Oooh... now they're using some sort of electric saw which has the same sound as the dentist's drill. My poor teeth...
So, if they fall through the roof, I'll at least have my loft bed to protect me...
