“If clicking with someone feels like you’re “on the same wavelength,” it turns out there’s a good reason for that. In what’s called “interpersonal synchronization,” people click in an unspoken meeting of the minds about how long to linger before a museum painting or when to get up from the coffeehouse table. Such synchrony occurs when an overheard remark triggers in both of you a simultaneously raised eyebrow, when what you see on your companion’s face reflects the feelings and thoughts inside your own brain. Your body language matches, what catches your attention catches his, you become impatient at the same time about the same things.”
