CLASS CAN BE defined as rank, tribe, costume, grooming, culture, acculturation, education, manners, and taste. Class also includes attitudes and assumptions. It is an implicit and explicit source of identity.
Joey was as different from me as dark to light. He was upper class, eloquent, and always tastefully dressed. He was educated at the best schools available, including a short stint at Yale, while I was gratuitously passed with benefit of remedial classes by my high school. He was brilliant and articulate, while I stammered incomplete sentences and mispronounced basic words.
