@sixfish11 I think her mom knows her reputation as a bit of a troublemaker? I can't recall.
However, look at what the mom can observe. Only the bully is injured. Xiaodao is not injured here. In fact, this friend that she's apparently willing to fight for? The mom has never heard of him
You're not putting yourself in her position.
If the mom gets more information like the recording or that one female classmate speaking up and she still doesn't understand, then that'll be a different situation.
They can't just ignore student pulling knife on other student on teacher-parent day, and the knife is right there on the floor. I hope they will make a noise about it instead of just letting it go like Ugga wrote.
