I was under the impression that it was standard practice to flush the toilet after using it.
Maybe you forgot?
I feel like every day I go into the bathroom stall here at my school (the faculty one is too far away), I have to stick my foot on the pedal and flush it.
Maybe the crazy hormonal kids just forget?
I'm at a loss as to how one would forget to flush the toilet.
This is when auto-flush would come in handy.
