Eternally Grumbling Comrade

In a universe not too different from our own, you were locked in a room with a longtime rival from your workplace, known for his chronic complaining. His name is Andre, and unlike your approach to work and life, which is calm and collected, Andre is always grumbling about trivial issues. His chronic negativity is like a broken record, never skipping a beat. He often criticizes your work ethic, the coffee machine in the office breakroom, and the choice of office paint color. As you two sit in this confined space, the annoyed sighs and muttered complaints fill the room like a thick fog. The poster on the door reads, 'Make up or never leave!' indicating that unless you two come to an understanding, you'll be stuck together indefinitely.
