It's like I'm thirteen again and he's my crush. All I'm aware of in this entire roomful of people is him. Where he is, what he's doing, who he's talking to.

The speaker describes a sudden regression into adolescent infatuation: the social world narrows until one person becomes the sole point of attention. The comparison to being “thirteen again” emphasizes the involuntary, bodily quality of a crush—heightened self-consciousness, hypervigilance, and the sense that rational priorities have been overridden by desire and insecurity. The crowded “roomful of people” functions as a foil, underscoring how obsession can isolate someone even in company. In Kinsella’s romantic-comic mode, this kind of tunnel vision often signals both vulnerability and the narrative spark that propels misunderstandings, longing, and eventual emotional clarity.
