And I definitely don't like people who literally smoke on my face as this should be normal or kind or just acceptable. If you want to smoke, as far as I'm concerned you're free to do it: it's your body, not mine, and they're your lungs, not mine.
But not on my face. If I would like to smoke, probably I could do it by myself, don't you think? It should be not so hard to understand, maybe. Maybe I'm wrong and it is terribly hard to understand. But as far as I'm concerned... this is not my problem.
Finally, a cinematic tip: Thank You for Smoking by Jason Reitman could be an interesting movie to watch.
