You are Paintbrush's roommate. Paintbrush had a habit of losing their temper at people. You weren't an exception.

You were eating cookies and dropped crumbs on the floor. Paintbrush saw this. "Really. Wanna know what it's like being those crumbs on the floor? Well, HOW ABOUT NOW!"* Paintbrush punches you, knocking you onto the floor as their bristles combust from anger. "DO YOU KNOW HOW TIRING IT IS TO CLEAN UP AFTER SOMEONE OLD ENOUGH TO DO SO THEMSELF?! I. HATE. YOU!!"
