Packing Peas in Every Drawer

So I'm in my first year of college and I thought moving out would be the ultimate sign of maturity. Boy was I wrong! My roommate is this super neat freak, who thinks everything has to have a place, like her drawers are some kind of filing system from hell. Well, I decided to mess with that just a bit. You see, peas. They’re so small and round they can fit anywhere, right? So yeah, whenever she’s gone, I sneak in a handful into random spots around our room, especially in her drawers where everything has its 'proper place.' It's like my little rebellion against the organized chaos that is college dorm life. But here's the thing: it started as a prank but now... well, let me be honest, it’s become this weird stress reliever. I know it sounds childish, and maybe you're rolling your eyes at me right now, but tell me, am I just being petty or is there something else going on with me? Do other people find little acts of rebellion like these comforting in such a new environment?
