What does Cherry say is the difference between Socs and Greasers in chapters 2 and 3 of The Outsiders?

Social and economic factors in The Outsiders by S E Hinton contribute to the perceived and professed differences between the "Socs," whom Ponyboy calls "the jet set, the West-side rich kids," and the Greasers, the boys from the "East side." The Socs seem to have everything: money, possessions, cars and influence. As Ponyboy points out, "They may be a public disgrace one day and an asset to society the next."

In sharp contrast, the Greasers are more like "hoods" and come from average or poor backgrounds. They are perceived as troublemakers and instigators, always causing a disturbance even when the Socs, arrogant and superior, are to blame. The Greasers and the Socs hate each other for no reason except that they are rival gangs from very different backgrounds, representing the class struggle.  

Cherry recognizes that Ponyboy is a little different from usual Greasers and Ponyboy recognizes her from school but thinks "...they weren't our kind. They were tuff-looking girls..." Cherry, who thinks that most Greasers are "trash," throws her coke in Dally's face when he gets a bit too smug but manages to hide her fear. She becomes friends with Johnny and Ponyboy because they defend her against Dally. She doesn't think of them as "innocent. Just not...dirty." She does however, have a respect for them all and, after hearing Ponyboy relate the story of Johnny having been beaten up by the Socs for no reason, she is anxious for him to understand that "not all of us are like that."

Cherry wants Ponyboy to understand that it is not that easy for the Socs. Ponyboy has always thought that it is "money" that separates the Socs from the Greasers but Cherry points out the different value set of the Greasers; "you're more emotional," she says. It is all very well for the Socs to be sophisticated but Cherry knows that this makes them shallow and "nothing is real with us." Socs are, according to Cherry, "always searching for something." From Cherry's explanation, Ponyboy recognizes that, just as the Socs feel nothing, the Greasers feel too much and "violently."
