Quote context

[...]

- It was a mighty peaceful sunset until old Josiah happened to sniff and he whispered to his wife: Mariah, will you also take a whiff?

- And Josiah and Mariah double-sniffed. And they said: I wonder if.

- But they really didn't wonder. They knew it was terribly true.

- They knew that the sour-sweet wind was coming back and what the sour-sweet wind would do.

- Inside, children.

- I suggest we stay indoors tonight. I suggest we lock ourselves in tight.

- Tonight, you know, won't go quite right. You can tell by the smell of the wind.

- It sounds like another one's coming. Another Grinch Night might commence.

- I wouldn't go out on a night like this, for a dollar and fifty cents.

- Always starts when that sour-sweet wind begins a-howling.
