It’s not harmless.
My son had a friend do just that a week ago.
The kids are devastated.
Context is everything. Did the teacher instruct him to do this? Probably not. NO one said suicide was harmless. What we have now are a bunch of whiners that are not taught to deal with LIFE. Not everyone will be kind nor is everyone your friend. Kids are not taught to pick themselves up and go on. Perseverance is a dirty word and Mom and Dad sue and complain. Kids don’t commit suicide because the teacher said something mean. If they do they had MUCH bigger problems going on. Remember “sticks and stones”?
