At one point in Looper, someone comes out of the crops in the dark and walks towards the woman. Joe jumps out to save her to find that the person isn't a threat and has a sign on them. I didn't catch what the sign said. What did it say?
Having seen the movie a second time, here's the text of the sign:
Once Young Joe saw the sign, he just gestured for the vagrant to leave, instead of shooting him.
