Why do you think Bud begins to cry and cannot stop?
In Chapter 15, Bud is invited to eat dinner with Herman Calloway and his band at the Sweet Pea. Bud is treated to his first sit-down meal at a restaurant and thoroughly enjoys his food. During the meal, Bud listens and laughs at Steddie Eddie and Jimmy's jokes. For the first time in his life, Bud notices how funny Jimmy is and how nice Steady Eddie acts. All of a sudden, Bud realizes that this is where he is supposed to belong. He feels an overwhelming sense of joy knowing that the Dusky Devastators of the Depression are the people that are meant to surround him. Bud can't help himself and begins to cry uncontrollably. The reason Bud cannot control his tears is because he is overjoyed to finally be around people who will treat him with compassion and care. Being an orphan who is on the "lam" isn't easy and Bud feels like he's part of a family after spending some time with them. His difficult journey has brought him to a place where he finally feels comfortable and loved. Bud's tears are an expression of the relief, joy, and happiness that he can no longer contain.
