The houses find a $20
I, a slytherin, was waiting in line for coffee with my hufflepuff. I found a $20 on the ground, only to have my puff immediately snatch it and turn it in to the barista “in case someone came back for it.” My slytherin ass knew that IF anyone did, that barista would keep it anyway.
A gryph would have held the $20 up and asked if anyone in the immediate vicinity has dropped it before pocketing it.
A raven claw wouldn’t have gotten caught picking it up.
