Anyway, I went on walking home, thinking about the movie, and then suddenly wishing I had some company. Greasers can't walk alone too much or they'll get jumped, or someone will come by and scream "Greaser!" at them, which doesn't make you feel too hot, if you know what I mean. We get jumped by the Socs. I'm not sure how you spell it, but it's the abbreviation for the Socials, the jet set, the West-side rich kids. It's like the term "greaser," which is used to class all us boys on the East Side.
