Saving my teacher

[A teacher stands in front of the class and points to a picture of a cigarette on the screen. Emma listens attentively at the back of the class.]
Teacher: “Smoking kills, so never start with it.”
[Now the teacher stands in front of the school, while smoking.]
My attempt to save my teacher’s life...
[Emma runs in a panic towards the teacher, ready to grab the cigarette.]
...was somehow not appreciated.
