I'm a smoker and like to think I'm a considerate one, ie, I wouldn't smoke in someone elses house unless they were smokers. However, if a neighbour knocked on my door and asked me not to smoke inside my own home I wouldn't give them the time of day as I wouldn't dream of knocking on their door for say a constant smell of curry or noisy shagging or whatever. In your own home you live by your rules as long as you are fairly considerate.
