DS has lately started Year 7. First food tech class. He has told me that another boy was waving a sharp knife at people and wouldn't stop when asked. My understanding is that he didn't approach anyone but was more... gesticulating with it, in a threatening kind of way? Another teacher was called and the boy was removed from the class and not seen for the rest of the day.
I've emailed DS' form tutor to say I am concerned about what he has told me, and asked what steps have been taken / will be taken.
AIBU to be quite disturbed by this? (YANBU) Am I overreacting? (YABU)
