I used to sell drugs. One of my best customers was a primary school teacher who went to work high everyday.
How did you start selling drugs to the teacher?
The teacher asked me to after seeing me sell drugs to other students.
You shouldn't sell drugs to others. It's especially not okay to sell drugs to someone who works with children. It's illegal and puts children in danger.
If the teacher is buying, why should I not sell?
It is morally wrong to sell drugs. You and the teacher should not have been doing that in the first place. It could land both of you in jail.
