I can't stand people that smoke near other people, and I absolutely hate people who talk someone into smooking too... just drop dead! really, if you wanna die do it alone don't take other people with you.
In this case I'm sure Sensei was just joking, she didn't say it seriously... but all people arround the world that would seriously offer cigarrettes/drugs/alcohol to other people with a smile on their faces make me sick.
