You were getting annoyed. In this big house, there had to be someone around, and all this junk around is making you irritable. So there was one option: Smash until you saw something.
You began kicking, your massive strength allowing you to destroy most of the stuff. You weren’t going to stop until you saw a door. If not, you’ll make one with one of the walls.
You smash everything in the room, and find nothing. Turns out smashing everything in a messy room, just makes it messier. As you’re about to smash a wall, you spot a door you didn’t notice before. It wasn’t hidden behind anything, you just didn’t notice it. The door seems to lead outside, based on the window next to it.
