Briefly describe Hiram’s argument for testifying and Grampa’s argument against testifying.

Hiram is afraid, but he feels that he must disclose what he knows. Grandpa, however, argues that Hiram didn't actually witness the crime and is basing his stance on a conversation he heard when R.R. was talking. Then Grampa changes course and declares that Emmett got what he deserved. Lastly, Grandpa notes that he doesn't want Hiram to embarrass the family like his father (Harlan) did.
