What do you think it means to “harbor” someone? How do the characters become harbors for one another?

Harbor means to protect and provide safety. The weekly chat the kids engage in at the ARTT Room becomes a safe space for them to share over time. Initially, the room was just that, a room, occupied by children from different backgrounds. Ultimately, they form an unlikely bond that entails emotional support and reliance which transforms into a strong friendship. The recurrent theme is the act of harboring someone in every situation in the same way they would hope to be harbored.
