Got to learn from that I know how he feels from experience. I was stabbed 7 times in the back by the guy i was fighting with's best friend. At the time I just thought he was punching me in the back, but later after it was over my friends and i were celebrating and i passed out, only to wake up in a hospital icu 6 days later.. Yes knives are very scary and we should all take precaution with approaching an assailant whether we see one or not!
