Bruno tells Shmuel that he was going to go.

Two days before Bruno leaved Out-With, Bruno and Shmuel met together at the same place.  Shmuel told him that his father went missing and he couldn’t find him.  Bruno told him that he is going to leave soon.  Shmuel was shocked and sad at the same time as nobody will talk to him anymore. They decided that Bruno will come over to the other side of the fence the next day to play with Shmuel for the first and last time. And they will look for Shmuel’s father too.
