Keep:
The book Aunt Bee is reading is titled "Camp Winokee for boys twelve to fifteen." Andy later says the camp is for boys 12 to 14.
Bee apologizes to the Hollander's maid that she's not dressed for visiting, but she's wearing a matching blue suit and hat, a pearl necklace, and white gloves.
During Billy's visit, Aunt Bee serves lunch on an elaborate silver dining set, as well as having a large silver sideboard setting. The Taylors would not have such luxury. Andy may have inherited a silverware set for his wedding, but this would be about the extent of it.
