At the beginning of the story Bruno comes home to his house with his maid packing his bags. Bruno will later find out that his father has been promoted by The Fury. So they are moving because of his Father's job
I am packing all your stuff up for your move Master Bruno.
Maria! What are you doing going through all my stuff.
The rising action was when Bruno went exploring outside of his new home and found a boy on the other side of the fence who was about the exact same as Bruno except they were on opposite sides of the fence.
Hello my name is Bruno.
Hello. My name is Shmuel.
The Climax was when Bruno saw Shmuel cleaning cups in his house and offered him some food and Lieutenant Kotler caught the two socializing and got mad at Shmuel because Bruno denied their friendship.
Don't lie to me again boy. We will have a talk later.
