Hey no fair!

I was just trying to hunt skunks at night and near Worthington Ranch near McFarland ranch and I found two men near a tent playing with TNT and I was like "hey what are these guys up to" and was cautious if they might try and shoot me but they ignored me as I rided closer and so I just walked slowly and close to them on my horse just pressing B to try and greet them then ride away and I kept pressing B but he just wouldn't do it and then suddenly the TNT just blew up and we all died! Why did it just blow up? Stupid! There was not even a firefight happening!
