What does Cherry explain as the difference between the Socs and the Greasers?

Answer: The Greasers are emotionally sensitive, while the Socs are not.

Explanation:

The Outsiders, S. E. Hinton's novel, tells a story about the two groups of friends - the group of rich kids known as the Socs, and their poor rivals, the Greasers.

Cherry is a girl that belongs to the Socs group, and she describes the different values of the two groups. The Greasers, according to her, are emotionally sensitive, which is not the case for the Socs. The Socs don't "feel", while the Greasers act on everything they feel.
