Might just be me, but...

Is it just me, or has my room been getting dirty more easily lately? (Feels negative to say it, but I mean it in a thankful way) I feel like I often think, 'Oh, I can clean it already,' I've redecorated my room and changed the characters I've entrusted with my keys, but I've never heard that those things affect how easily the room gets dirty. Is it just my imagination? A silent update?
