I work at a school.
There are some students supposed to be doing supervised revising.
My boss is supervising.
They are playing with firecrackers.
One of them throws a firecracker at my head.
As I approached the students so did he.
I told him what happened (it missed me by millimeters and hit the wall behind me).
He said, 'yes, I know they have them,' and pointed out the cartilidge on the floor.
I reiterated that they threw it at my head.
He ignored me, carried on talking to them and laughing (one of them even complained that their firecrackers weren't working. He said it was a shame).
I therefore asked myself for them not to do it again, feeling like I was being unreasonable for being cross because of his (lack of) reaction.
So... I am ridiculously cross. AIBU to tell someone about this/complain?
