THEN ... make note of every line in which you find "positive sides" and every line in which you find "negative sides" -- and put those line numbers in different columns.

Go back and reread all the positive-sides lines. What do these lines have in common with each other?

Go back and reread all the negative-sides lines. what do these lines have in common with each other?

Let us know what you come up with.
