we got lucky and parking was only like, $5 at my high school, and there were so many people who qualified for free/reduced lunch that they just gave everyone free lunch. but it was still like $80 just for the cap and gown to graduate, and ofc if you wanted to buy the composite pictures they took before graduation, that was pricey. we didn't have a homecoming dance because my classmates are terrible, but prom i think was at least $20 a ticket.
so yeah i at least had a cheaper experience than most, but it's still wild that you're required to pay money to graduate when you've already put in 4 years of work to get there
