I was gutting a cow and i heard "hey player" and turned around and was completely surrounded.... lol I felt like a noob letting them get the drop on me, but they let me go, and I offered them food as my condolences. It seems safest to get the drop on someone, and let them leave if them respond while your weapons are still fixed on them. I try to be friendly unless im near hot spots (stary airfiled gstores ect)
