I'm a smoker yeah and sorry if I offend you but aww man ! I think people like you are kinda selfish since only smokers have to be considerate but you, non-smokers think you have the right to say whatever people have to do or not. That kills me. And come on, of course you can leave the room and it's not with 5 minutes in contact with smoke everyday, you will be automatically sick.
Of course I can see your point and I know how upsetting it could be but come on, everybody should make some efforts, not only us (smokers).

Edit: For your nan, I do understand and I couldn't have said it better myself.My nan had the same thing and it was a disaster. It's really upsetting because you cannot help her.
