My teacher asked why I always bring my gym shoes to school but wear them home on the bus

I tried to explain it's called forward planning.

I bring the shoes. I attend the class. I participate in the bare minimum required dodgeball. Then I wear them home because my locker smells like a cheese graveyard and I'm not opening that thing twice in one day.

Punchline

She said that's not how gym shoes work. I said that's not how her gym shoes work.
