I had just finished going to the bathroom when I smelt smoke.
Suddenly Dave left a stall with the heavy stench of cigarettes leaving with him. He then proceeded to ask me if I want a cigarette.
Quickly I remembered what my health class taught me. I told him no in my assertive tone which left him confused but he backed off a little bit. He then asked again and I acted like a broken record, repeatedly telling him no and that I had to get to class again in an assertive tone.
Despite me telling him no he continued to ask. I then told him that my mom would say no but this time I said it in a passive tone and this gave him a grip on me he wouldn't have had before if I had been assertive. I finally told him that I would tell someone if he asked again and he finally gave up.
When he gave up I used the opportunity to tell him how bad smoking was. I told him that it would hurt his lungs, give him lung cancer, give him throat cancer, make him more susceptible toward colds, and that he would have a higher risk of heart disease. This moved him so much that he threw away his cigarette and thanked me.
