Greet them

Intentionally holding your hands up to show you have no weapons, you call down "Hello!" The men snap to attention, grabbing their shotguns and pointing them at you.

"Hey hey hey!" you say, raising your hands higher. "I just want to talk!"

"Then get down here," says the taller, darker man. "But leave your bag up there."

You do as requested, dropping your bag then immediately putting your hands up. You walk around the side small cliff, coming down around the hill to the men.

They both look you up and down. "How're you so clean?" the second man questions.

"I was in a bunker for the last few years," you say, before immediately following it up with, "but it's out of supplies and clean water now." That's a lie, but you're worried these men will try and break in to the bunker barely big enough for your 3 family members.

"Hmm," the taller man says, before putting his gun down. His friend does the same. "Alright, I believe you. What do you want?"

"I want to know how to survive out here. Everything seems so...dead, how do you eat?"

"You just have to know where to look," the shorter man says. "But why should we tell you? There's so little food as it is."

Damn, you didn't think of that...
