How would you react if.... you saw men with guns.....?

[My Good Babushka]

28. I'd give them a wide berth

and go about my business. Whatever their intentions. They have weapons, are probably of the over-confident variety of people that always assumes they know exactly what a gun will do, the kind of people who have guns fall out of their pants, or go off when they are cleaning them, or "playfully" point it at others, taunting them that it "can't possibly go off". They probably have friends who likewise have guns, and maybe they are having personal grievances against some of them, maybe one of them will show up, maybe someone is sleeping with someone else's spouse and things are about to come to a head.
There are all sorts of complicated situations that are never improved with the presence of weapons, so I'd give them a wide berth, go about my business and come back when they've gone.
