Why is Jem crying at the end of the seventh chapter?i want to know why Jem is crying at the end of chapter seven
At the very least, Jem suspected that Arthur "Boo" Radley was the one leaving gifts in the hole in the knot hole in the tree. In fact, considering that he seemed convinced that the gift giver was a "mister" or "sir," which was obvious when he and Scout wrote their letter of thanks to him, Jem was probably confident of his identity.
Not only was the anticipation of discovering new gifts exciting, but it also revealed a kind, childlike nature found in Boo Radley, who was the giver. Jem, who was sensitive to the feelings of others, found it heartbreaking that someone would have filled in the hole and taken that link to the outside world away from Boo; it was especially disheartening and upsetting to know that his own brother treated him so. Jem must have felt that Boo had been treated cruelly enough by society, and specifically his own family, to have deserved the happiness of sharing things via the knot hole. The pain and frustration that Jem felt was compounded exponentially by the inability to thank the giver (Boo) for his kindness and generosity; Jem and Scout were unable to leave their letter for Boo, since the knot hole had already been filled with cement by the time they arrived with their envelope.
