The "funniest" non-smokers are ex-smokers. Funny in the head, that is.
A non-smoker is someone who has never smoked, whereas an ex-smoker is somebody who has smoked, but who chose to quit smoking. Non-smokers have no idea what smoking is all about, so basically anything they have to say about smoking is "boring." They simply do not know. On the other hand, ex-smokers tend to fall into two camps; those who no longer smoke and get on with their lives, and those who decide to make it their mission to persecute smokers. I fall in the former camp, preferring to allow people to do whatever they want with their short time on earth, whereas others prefer to have a go at those who haven't achieved the same "level of realization" as themselves. I laugh in the face of those who choose to make their quit everyone's quit.
1) You're unsupportive!
"I quit, and therefore you should quit! In fact, everyone in the world has to quit to support me, because I'm me! If you don't agree with me, then I reserve the right to bite your head off, and then ask you to comfort me while I cry in your arms."
2) You stink, and everything stinks!
"Since I stopped smoking, YOU started to smell really bad. Regardless of the fact that I also used to stink like hell and never gave a damn about it, it's now your problem, because YOU didn't stop smoking like me, and now I reserve the right to be rude to you for STINKING LIKE HELL."
3) I decided to live, so why are you committing suicide?
"I contracted a hideous disease, and therefore you will too. I stopped smoking to prevent further development of my disease... Why the F do you continue to smoke? Are you completely insane?"
These are just a few examples of things that really annoy me. I'm sure there are plenty of others...
I chose to start smoking, and I chose to stop smoking. It was MY choice. I don't judge smokers, ex-smokers or non-smokers any differently than before, during, or after I quit.
It is my life, and you should make it yours.
