Near-midair encounters occupy a peculiar place in aviation. They are not common events, but they are not rare either. Ask almost any experienced pilot and you will eventually hear a story about another aircraft appearing suddenly, far closer than anyone would prefer. General aviation operates in a system built largely on shared responsibility.
Unlike tightly controlled airline corridors or military formations, much of the GA environment depends on pilots seeing each other, communicating clearly, and maintaining constant situational awareness. Most of the time the system works extremely well. Occasionally, however, the margins narrow, and those moments can leave a lasting impression on a pilot.
