When my lease was up on my flat I thought about sharing but the amount of fuckin weirdos I met whilst looking was unbelievable.
My mates have asked me loads to share with them but I think that's a bad idea if you want to stay mates, lol
I wouldn't want to live with a scruffy bastard who never cleaned up or a bore who never went out. But I wouldn't want to live with someone who partied all the time...because I have no will power and would never go to work, lol
Whoever you end up sharing with, I'd set down the ground rules from day one so there is no misunderstandings..good luck
