The phrases I picked out are
"... He picked my grandmother... Her name was Bernice... Same like Bernice."
"Now our granddaddy's name was Boy Willie. That's who Boy Willie was named after."
The piano is important to the family because the first Boy Willie carved it, and they went through a lot of trouble to get it. The conflict is that the brother - Boy Willie wants to sell the piano, and the sister - Bernice wants to keep it. In my opinion some things are just too meaningful to sell or give away. That piano was inherited down because it tells a piece of the families history. They should not sell it.
