How does Pax know that he can safely leave the food tent while Peter's father is in there? Peter's father can't smell Pax, so Pax knows he can safely leave if he's very quiet. Peter's father doesn't see Pax, so Pax knows he can get to the tent flap if he stays behind things. Peter's father is focusing on the opposite side of the tent from where Pax is hiding. Peter's father gives Pax the signal he used to give him at home that meant "go through."THE HISTORY OF THE PAX
