The Radley's consist of Boo (Aurther) Radley, and his brother Nathan Radley . Their parents have passed away and Nathan has moved in with Boo to continue what his father has started.
When Boo was younger he and some friends played a prank a sherif. Then one of his friends made him angry and he cursed in front of a lady. This was illegial back then and was a minor misdemeanor, but his father saw it diffrently and locked Boo up in their house.
Nathan Radley came to fill his fathers shoes after he passed. Nathan also belives that Boo should be locked up for life in the house and not be aloud to speak to anyone. Boo wants to interact with the outside world so bad, but his brother and his father are his walls. The only outside interaction he gets is with Jem and Scout untill his brother finds out and puts an end to it.
The song below reminds me of Boo and his containment and constant longing for outside interaction. Boo (Arther) Radley is alo considered a mockingbird of the novel. He was just being a kid and messing around with his friends and the little prank they played got him locked up in his house for years and years and it tore him apart and turned him into a different person who started to take his anger out on his dad.
