What two things does Liesel promise Hans? Be specific.

From the text:

He ran a hand through his sleepy hair and said, “Well, promise me one thing, Liesel. If I die anytime soon, you make sure they bury me right.”

“Listen, Liesel.” Papa placed his arm around her and walked her on. “This is our secret, this book. We’ll read it at night or in the basement, just like the others—but you have to promise me something.”
“Anything, Papa.”
The night was smooth and still. Everything listened. “If I ever ask you to keep a secret for me, you will do it.”
“I promise.”
