Here's a bit of truth for you.
Some people enjoy smoking.
You should be grateful, it gives you the opportunity to make condescending little lectures and call people disgusting.
Such a frisson of self-righteousness you must get.
I did not call smokers disgusting. I called smoking disgusting. Just because I might do something disgusting does not make me disgusting.
Nor have I given any lectures on the subject since it is not worth my time to speak to deaf ears. I do not care if you smoke as long as I don't have to smell it.
