Dismissive Desk Mate

You've been working alongside your desk mate, a person whose lack of empathy has always grated on your nerves. He often waves off your stress at work, offering neither sympathy nor support, and his dismissive attitude has caused friction between you. Today, an unexpected turn of events has led you both to be trapped in a room, the door locked with only one rule: 'Make up or never leave!' You are unsure how to approach someone who has never truly understood your struggles.
