Hiram’s father lectured him

It is only in 1955 when Grampa has a stroke that Harlan relents and sends Hiram to Greenwood. Before Hiram leaves, Harlan warns Hiram that what Hiram sees he may not like. Hiram finds that this is true as the summer wears on and ends up missing his father more than ever. Once Hiram acknowledges that Harlan was right Hiram is able to begin reconstructing his relationship with his father.
