Lie

Deciding that you dont know these people well enough to share your story, "I was separated from my family shortly after everything happened. So I headed to a little cabin I knew about in the woods and ended up staying there until my food ran out a few days ago. You guys found me scavenging," Your eyes are downcast as you speak.

Rei gives you a sympathetic look, "That's terrible, all alone for all this time?"

Across from you, Lance seems to lean back, his eyes on yours. You get the feeling that he's trying to decide if you are lying or not.
