I only wish I hadn't... But except on this one occasion. When my getting ticked off actually did some good. In any case I hardly ever lose my cool at all. But yeah as teenager I tended to be more temperamental, though now I believe most of it was deliberate and put on.
That said what that pizza delivery guy did was just horrible. He sure needs anger management classes,pronto!
Finally I believe anger and acting when angered can cause much conflict and adverse effects, ruin relationships, and bring on much pain. Always best avoided...
