What does cherry explain as the first difference between the socs and the grasers?

In "The Outsiders," Cherry explains that the first difference between the Socs and the Greasers is their social status and the way they express their emotions. Socs, coming from wealthier backgrounds, often hide their feelings behind a facade of coolness and indifference, while Greasers are more open and expressive about their struggles and emotions. This fundamental distinction highlights the divide between the two groups and sets the stage for the conflicts and misunderstandings that arise throughout the story.
