Builders are twats - FACT!
'You've not taken the wall paper off, I can't plaster over that'
'Erm, you were going to strip the entire wall back to stone, why are you plastering over anything?'
'Na, I'm using this now....'
'Maybe a heads up wouldn't have gone a miss' 
Queue me rushing round the village trying to borrow a bloody steamer! Got one, and they've only just started to use it!
Then the same builder was removing the wall and hit a live electricity cable, shocking himself and trippping the entire house! 
I turned all of the sockets off and left them too it, took Nemo to playgroup after having a mini meltdown!
Then I come home to a crumpled DH who is all 'there's no power in the lounge, the plugs must have blown, what are we going to do, do you know a spark?'
Or we can just turn the sockets back on? 
What a bloody morning!
Hydro next and then the docs xxxxxx
