What questions does the blind man (Robert) ask the narrator?

From the text:

“Are those fresco painting, bub?” he asked, and he sipped from his drink.

“That’s all right, bub,” the blind man said. “Hey, listen. I hope you don’t mind my asking you. Can I ask you something? Let me ask you a simple question, yes or no. I’m just curious and there’s no offense. You’re my host. But let me ask if you are in any way religious? You don’t mind my asking?”

Then he said, “I think that’s it. I think you got it,” he said. “Take a look. What do you think?”

But I had my eyes closed. I thought I’d keep them that way for a little longer. I thought it was something I ought to do. “Well?” he said. “Are you looking?”

My eyes were still closed. I was in my house. I knew that. But I didn’t feel like I was inside anything. “It’s really something,” I said.
