Answer:
Friends is not what is on the outside , it's what in the inside .
Step-by-step explanation:
like in the chapter , Bruno had to lie that he was not a friend of Shmuel , he didn't intended to lie but he got scared to be beaten . Though he lied , he still apologized to Shmuel later on and gave him food with his hands and it was the first time they had ever touched each other before .
Other lesson we learn is - People are not to be extracted , they are meant to be closer
Hope this will help
