And erm, one day we had friends round, and I went into the loo  it stinks of smoke in here, it was really bizarre, and I, I went, and sort of just thought oh, and then I went in again, and I really did smell, and I thought, this is really odd, and so when I came out here I said, did anyone else smell smoke in the ba in the bathroom, and they said oh yeah, I could smell cigarette smoke, and then, it must have just been upstairs, and it wafted down, and in through ours, cos there was no one else really around.
