Every day, I try to stamp only as many date due cards as I think we'll need. It's a game to me, to see how close I can get. Recently though, my assistant has been messing with this game. Around 1:00, he stamps like 50 cards, even if we don't have any more classes schedule for the day, thus completely ruining my game. The worst part is, there's no way I can ask him not to stamp the cards unless I confess about the game and reveal myself to be a total weird-o.
