How does Jaggers react to the visitor?

Jaggers doesn't want to know anymore than he has to.... he cautions Pip as to how he must relate the meeting.

From the text:

"Now, Pip," said he, "be careful."

"I will, sir," I returned. For, coming along I had thought well of what I was going to say.

"Don't commit yourself," said Mr. Jaggers, "and don't commit any one. You understand--any one. Don't tell me anything: I don't want to know anything; I am not curious."
