I examine a confrontation that was 100% avoidable - and demonstrates why understanding human nature is your most valuable self-protection skill. This footage shows what happens when someone decides to be the "hall monitor" and moves a stranger's parked bike without permission. The bike owner's response was swift, violent, and completely disproportionate - a textbook example of how quickly an everyday interaction can escalate to serious injury. What's the lesson? You never know who you're dealing with or what kind of day they've had. This "enforcer" may have been the fifth person to confront the bike owner that day - becoming the unfortunate recipient of accumulated rage. Understanding human psychology and reading people correctly could have prevented this entire incident. This is why I consistently recommend books like Robert Greene's "Laws of Human Nature" and "48 Laws of Power" - they teach you to recognize and navigate human behavior as it actually is, not as we wish it to be.
