The man handed her the money and promptly walked away without the book. The girl saw him leave empty-handed but she didn't call out to him in any way. Why?
An old man wanted to leave all of his money to one of his three sons, but he didn't know which one he should give it to.

What were the two things that the man bought and what was able to fill the room?
