Intro
*Handouts are passed down from the front. Written on the paper is an "Announcement for Parent-Teacher Observation Day."
That time of year has finally come.*
...How am I going to hide this?
This observation day system was only introduced this year. The school claims it's so "families can see the students' growth." It's exasperating to have observation days even in high school.
You head home with a heavy sigh.
