Interesting Read from today's class

So I am teaching one very small class on Tuesday and Thursdays. We are reading Charlotte's Web. I just finished teaching the class and decided I just had to post a brief quote from the book. Interesting to read and even more interesting to try to explain the meaning.

"'What do you mean, less than nothing?' replied Wilbur. 'I don't think there is any such thing as less than nothing. Nothing is absolutely the limit of nothingness. It's the lowest you can go. It's the end of the line. How can something be less than nothing? If there were something that was less than nothing, then nothing would not be nothing, it would be something- even though it's just a very little bit something. But if nothing is nothing, then nothing has nothing that is less than it is.'"

Talk about a confusing class. But so entertaining to discuss.
