YANBU to be pleased when he's gone - DH and I had DH's best friend living with us in London for 5 weeks a couple of years ago as we had a spare room and he had no money for rent. We had to lend him his first month's wages too as he was skint (he did repay it as soon as he was able to). He was no trouble, he didn't impinge on us very much at all and he had his own room but it was still lovely when he moved out - we could walk nude from the bedroom to the bathroom, go to the loo with the door open so as to continue conversation with the other person in the living room and generally lower our standards of behaviour to their usual poor level. Bliss.
