I've had knives pulled on me a couple times, and a gun one time. I also had a crazy Nazi tweaker threaten me with a homemade hatchet. But I grew up on the wrong side of the tracks, and continued associating with a lot of the wrong people into young adulthood. The first half of my life was very far from average. What's interesting is that those experiences never really leave you. I live in an extremely safe area now, but I'm still hyper aware of my environment when I'm out, and I spot potential threats long before my friends are aware of anything sketchy.
