What does Rosalie say truly touches Maverick's heart?

From the text:

“But he wanted to stop,” Ms. Rosalie says. “He told me, ‘Grandma, I can’t stay in this. Mr. Maverick said it only leads to two things, the grave or
prison, and I ain’t trying to see either.’ He respected you, Maverick. A lot. You were the father he never had.”
