Bruno was told to never go near the fence. However, he did it anyway and discovered a boy. They started talking and both realized they have the same exact birthday. They talked about other things and got to know each other. Bruno finally left and did not say a word about this new friend he discovered.
As Bruno was reading, Gretel walked into his room. He asked her why are those people inside of the fence. She responded because they are Jews and no one like them. He then slipped and said I better go see Shmuel he is probably waitin for me. She was confused so he made up a lie that Shmuel was his imaginary friend.
A couple of days later after the "imaginary friend incident" Bruno walked into his kitchen to see Shmuel there. He asked what was he doing and he said they had a job for him to polish the glasses. Bruno then convinced him to have some food and he finally agreed. Lietant Kotler then yelled at him and Bruno made believe he was not his friend and Shmuel got in trouble. He felt very bad about this.
