![There’s No Such Thing as Everlasting Love (According to Science)
It is what she calls a “micro-moment of positivity resonance.” She means that love is a connection, characterized by a flood of positive emotions, which you share with another person—any other person—whom you happen to connect with in the course of your day. You can experience these micro-moments with your romantic partner, child, or close friend. But you can also fall in love, however momentarily, with less likely candidates, like a stranger on the street, a colleague at work, or an attendant at a grocery store.
