My Math Book Hiding Spot

So there I was, cramming before my final math exam. I looked around the room and saw that old desk drawer where I keep all sorts of junk no one else wants to touch. And in a moment of desperation, I stashed my brand-new math textbook right inside. Yeah, my professor said we could use it for notes during the test, but I figured hiding it would make me feel like less of a cheater. Now that the exam's over and I've been back at home for days, I'm still debating whether to go confess or just pretend nothing happened. Honestly, part of me feels relieved no one knows, but mostly, I just feel dumb.
