This exchange highlights the crux of Albus and Harry’s problems. Initially, their struggles are based on the fact that students compare Albus and Harry. But here it also becomes clear that Harry is trying to evaluate Albus’s experiences based on his own childhood. For Harry, Hogwarts was an escape from a terrible life with the Dursleys.
