An acquaintance just came to the door to borrow something. He's a very charming older gentleman, and the husband of our local parish councillor. I'm very fond of him. Anyway, he was obviously in mind for a chat which was fine, but halfway through he lit up and blew lots of smoke into my house! I'm a bit sad as I really like and respect him, but surely that was a bit unreasonable? My house smells of fag smoke now!
Plus I'm an ex smoker and it took every inch of willpower not to ask him for one
