Holy fuck

My house is old, it’s a piece of shit. There’s a random chimney that runs though a corner of my room. The squirrels have discovered that they can climb down the chimney and live amongst the walls or ceilings or wherever in my room. There’s this persistent fucker of a squirrel gnawing or scratching at something in the wall beside me. I’m trying to get some work done and this guy just doesn’t understand that bashing my fist on the wall means go away.
