This friend and I will go out that night. We both smoke. So I asked her to smoke before we head out. Then there's something I noticed. SHE DOESN'T REALLY SMOKE! As a smoker I was so frustrated to see someone who waste their cigarette. I have low tolerance for that. I cannot let her do that for the rest of her life. So I teach her how to smoke that cigarette. We both smoke twice together til she get her lungs filled with smoke.
