She raises her hand] Miss Peters: Mary Sue! Jennifer: Yeah. What's outside of Pleasantville? [the entire class turns to look at her] Miss Peters: I don't understand. Jennifer: Outside of Pleasantville? Like, what's at the end of Main Street? Miss Peters: [chuckles and shakes her head] Mary Sue. You should know the answer to that! The end of Main Street is just the beginning again. [the teacher points at the intersection of Elm and Main. The class feels released to giggle at Jennifer/Mary Sue's clearly stupid question, and Jennifer frowns again]
