Its not only that, misunderstandings happen ALOT, especially when drinking is involved. I was out in Albany once, and some kids were yelling back and forth while I was walking to my car with a few buddies. Before I know it I have 2 dudes running up on my with knives ready to do work. Luckily I have pretty good negotiating skills(:lol), and talked my way out of something I had nothing to do with. Ive had one on me ever since that. After a few encounters with knives/guns Id much rather be prepared to defend myself if need be!
