When I was in high school, a gang from my school had "beef" with some other students from another school leading to some tension between students of both schools. One day, one of my friends got jumped by 4 of those students and was holding them off. One had an aluminum baseball bat, two had knives and the other a machete and my friend had a knife but was managing to hold his own but was tiring. I immediately jumped in brandishing my knife as well(school was extremely dangerous back in the days) and fought off three of them with the other one running when he realized that I fought off his other friends and they retreated. I was going to chase after them but my friend collapsed from exhaustion so I tended to my friend.
