...one says to the other, "How's it going?"
The other, only making very brief eye contact, replies, "Not much."
The first says, "Hm?"
The second says, "What?"
And there's an awkward pause where they realize not only that the comic shop that used to be there is not in fact there anymore, and they are quite apparently in a bar... but that they are so terrible with small talk that they failed to notice for a near minute... then they try to leave at the same time, and they can't figure out who's gonna walk through the exit first, and they do that awkward slow lean and half-step toward the door rapidly (but silently) changing from "Okay, I'm gonna go" to "After you" and back again via the most uneasy set of body language gestures, some of which the other is not even catching because they're so rampantly trying to avoid eye contact, all while the one INTP is holding the door for the other thinking to himself, "Go," while the one he's holding it for is going, "I'M SO CONFUSED," and then they both think, "Why the fuck is Rascal Flats playing in a bar on the north side of Chicago?"
And as they look at each other in that moment, they realize, "Oh my god. I left my Super Nintendo on," and they immediately work out their exit strategy and go back to their respective homes.
