Where does Nathan Radley, Boo's brother in "To Kill a Mockingbird," demonstrate anti-social behavior?
Nathan Radley demonstrates anti-social behavior near the end of the sixth chapter. He shot into the air to scare off the man he saw in his cabbage patch. He told the neighbors that the next time he saw someone in his patch, he wouldn't aim high. This portrayal of Mr. Radley with a loaded shotgun across his arm, speaking of doing whatever it takes to keep people out of his "patch" is a potent symbol which demonstrates his less than social and protective nature.
Also, in Chapter One, although he does not directly take action, it is stated that the neighbors believe that Mr. Nathan Radley was just as mean as his father was, and the only thing distinguishing them was age. This is a foreshadowing of his nature and anti-social role in the novel.
None of the Radleys, except Arthur of course, show any indication of wanting to be social. Nathan merely continues this trend. The history of the Radleys, played out by the kids on Atticus's front porch, is testimony to the family's isolation from the rest of the town.
The great travesty, however, is not his own reluctance to socialize with his fellow townspeople, but his destroying his brother's small attempt at connecting to the outside world. By cementing up the knot-hole, Nathan shows his awareness of Arthur's leaving gifts for the Finch kids. Sadly, he also shows that he disapproves of even this small attempt by his brother to reach out to others.
Nathan Radley spoils his brother's secret game with the children by filling the empty tree hole with cement. He may have been ashamed of his odd brother and/or wanted to protect both his brother and the children from things he imagined Boo might do.
i am doing the same project you are i bet... i believe when he fils the knothole with cement could be considered anti-social. this takes away books way to communicate with anyone. or another one is that it says when he comes back from town and the kids talk to him, all he did was cough. those i believe are both examples of ant-social behavior
