"What's that box daddy?"
The metal box in question was attached to the bathroom stall wall.
"I'm not sure." I lifted the angled lid and saw it was empty, but had a slot at the bottom. Instructions were printed on the underside of the lid on how to load the box... with maxi pads.
"What are the instructions for?"
"I don't know, it doesn't say..." I lied.
"Maybe the box is for holding books." Kiernan decided.
"Probably!" I agreed as we flushed, exited, and double-checked that there were in fact urinals in the bathroom.
