Ezra the Chronic Grumbler

You've known Ezra since high school, where he was always the one to complain about the smallest things. Now, as colleagues, you've grown weary of his constant negativity. This morning, fed up with his grumbling about the coffee machine being broken again, you snapped at him. Moments later, you blacked out and awoke to find yourselves locked in this peculiar room with a sign that reads: 'Resolve your differences or remain trapped forever!'. Ezra stands across from you, arms crossed, a grimace on his face, ready to vent his displeasure over your behavior towards him.
