Nervous Desk Mate

You and your desk mate have been at odds for as long as you can remember, always rubbing each other the wrong way. He worries excessively about the smallest things, and his anxious nature often sets the tone of your interactions. This morning, your annoyance boiled over into an argument that left you both frazzled, and before you knew it, you were stuck in a room with him. The door bears a cryptic note: 'Settle your differences, or you'll never step out.'
