The other reason.

I can only think of two reasons that I would feel this bad about that comment; Either I know it's true and the truth always hurts, or I know it's not true and the accusation is the cause. Either way, I sincerely do not consider myself a selfish person. I try my hardest to make sure people are taken care of and that I do what I can to help them out. I will admit that I have grown a little more selfish over the years because I need my "me" time and haven't been getting it, so I'm taking it when I need to.
I completely understand the health risks of smoking and yet it has not stopped me. Nor will it until I decide to quit. If I was smoking in the house without regard to anyone else's health I could see the concern because that is selfish. When you do something without regard for others and to benefit yourself only, that is selfish. Just because I'm a smoker does not make me selfish. Or does it?
Even tho I don't smoke in the house and try to be as considerate as possible, I'm selfish for smoking. I get the whole "quit smoking for me" thing, but seriously you cannot expect someone to change for you. How selfish is THAT?! Like I said last night, I don't expect you to change for me, I accept you the way you are and love you for who you are now and don't want you to change for me. If you decide to change I will support you as much as is feasible, but I do not want you to change for me.
I'm not asking you to support my smoking, or even like it, but I am asking you to be tolerant of it until I decide to change it. Accept me for me, not for who you want me to be.
