Three months later, the other students haven't gotten any better.
Sable skips school every few weeks, and she regularly has screaming arguments with her parents about the homework she hasn't done and her lack of motivation. They want her to just buckle down.
Things finally come to a head one day, and she tearfully demands to know what the point of it all is.
The answer of "get good grades, eventually get into a good college, graduate with a good degree, and get a well-paying job," does not improve her state of mind.
That... really is all pointless. It's just an endless cycle of pointless work to get pointless rewards in the company of people who hate you for trying to be yourself. It's never actually going to be worthwhile, never going to mean anything to anyone. Something breaks inside her.
She screams. She sobs. She storms back up to her room, cries to herself for hours.
Eventually, in the early afternoon, she leaves the house unnoticed, catches a streetcar, heads down to walk along the river.
