Every Duel you missed

A 34-year-old accountant reports three episodes in the past 12 months in which minor frustrations, such as a slow internet connection or a spilled coffee, triggered sudden rage in which he smashed his phone, punched a hole in a door, and broke a chair, each time without planning and without seeking anything from anyone. He feels ashamed and apologizes afterward, his partner is considering leaving, and collateral history shows no childhood rule-breaking, lying, theft, or legal problems, with steady employment and debts paid on time.
