In a meeting with school administrators, they will tell you the Cavalier* is not a threat.
The energy required to not scream and throw everything
you can get your hands on The trauma of knowing exactly who
the Cavalier is and that you’ve failed to keep him out of your child’s school will mean
you will throw up next to your car immediately after, shaking with the effort it took
to be the perfect victim/mother:

poised, calm, trying to remember every question you were supposed to ask,
and just generally not losing your every loving fucking mind.

Later, recalling that the HR Director lied to your face,
that they told you he’s in charge of the sex ed curriculum at your child’s school,
that when you asked for them to make reporting violence and harassment more clear
they asked if you could help them with that,

you will wish you had thrown up across the table, wiped your mouth stood up and said,
“Clean this fucking mess,” and walked out.

It would have been the least they could do.
