Connie and Arnold are very similar in the way they both have façades that hide big portions of their identities.
Arnold presents himself to be in Connie’s age group, but as the story progresses, there is evidence to support that he is not. When Arnold is introduced to Connie, she notices odd things that someone her age wouldn’t do. He, for instance, runs through many sayings as if he learned them but doesn’t know which one to use. Oates says, “Don't hem in on me, don't hog, don't crush, don't bird dog, don't trail me," he said in a rapid, meaningless voice, as if he were running through all the expressions he'd learned but was no longer sure which of them was in style, then rushing on to new ones, making them up with his eyes closed”
(12).
Arnold also is caught hiding that he knows who Connie was with the night prior and what her family was doing. Oates describes this instance “Aunt Tillie's. Right now they're uh—they're drinking. Sitting around,’ he said vaguely, squinting as if he were staring all the way to town and over to Aunt Tillie's back yard” (9). These eerie instances suggest that Arnold Friend is more than what he says he is.
