"I've got this obsessive compulsive disorder where I have to have everything in a straight line or everything has to be in pairs. I'll put my Pepsi cans in the fridge and if there's one too many then I'll put it in another cupboard somewhere. I'll go into a hotel room and before I can relax, I have to move all the leaflets and all the books and put them in a drawer. Everything has to be perfect."
