"Woah, woah, no need for the aggression!" Justin chuckled, extending his arms out in front of him, hands up. 
"See? Not drawing a weapon, not trying to advance towards you to take anything." He stood rooted to his spot on the main road, although a rumble of thunder from the south indicated that he would have to get off the main road soon. With so many buildings, it would be easy to find a place to wait it out, but this ebony haired vixen might be a rabid survivor of yet another raid. She had the frenzied look, the tattered clothing, the nervous stance, but something told him from the lockbox that this wasn't the normal "refugee-on-the-run" he encountered frequently in his travels. Why was she guarding it that closely? Might have had some family heirlooms, but in this age, why guard something that had only sentimental value?  Hold onto the past? She didn't look much older than him, so there wasn't much past to grasp. In any case, she looked like she could use a place to call home for a few days. He motioned to the pack on his back as he told her:
"Ok, look, going to get out a packet of raisins...raisins. You know, the dried grapes. For you to eat." He slowly got on one knee and took his pack off, rummaging through it to find a small plastic bag that was tied. Zipping the pack shut, he placed the bag on the ground in front of him. 
"Take them and eat. You're going to want the energy to get through the storm that's coming." The drizzle that had been descending picked up slightly in pace, as if on cue. Thunder rumbled once more, this time closer. 
"We can get into a building nearby, out of the rain. You can eat, I can start a fire and we can have a friendly conversation instead of you waving a knife at me. That sound ok? Cause I know it sounds ok to me." He drew a bit closer, picking up the bag of raisins and extending it out to her. 
"Come on, they're not poisoned." He waved the bag at her, his best smile coming across his face. Yes, it was dangerous to try and help, but more often than not he had learned that helping people in this world amounted to more good than evil. It was the optimist in him.
