Isn't it wild how this applies to regular arguments too? I've caught myself getting ready to fight about small stuff, then a deep breath changes my whole reaction. That pause feels like giving your brain a chance to catch up with your feelings.
Used to think taking a breath was just avoiding the fight. Then I almost snapped at my roommate for leaving dishes out, but paused and realized I was actually stressed about work. That tiny space lets you see what's really bothering you instead of just reacting. Now I try to count to three before saying anything when I feel that heat rising.
