Sonder vs empathy
Sonder names the recognition that other people have vivid, complex lives of their own. Empathy is the ability to understand or share another person's feelings by imagining their situation. Sonder can prompt empathy, but recognizing that someone has a full life is not the same as understanding what they feel.

Fictional scene
Not just background characters
From a café window, one person notices a traveller, a parent, a cyclist and other people absorbed in their separate days. For a moment, the passing crowd stops feeling like background.
The luggage, flowers and everyday tasks are prompts to imagine lives continuing beyond this one glimpse. The picture cannot reveal those people's private stories. It illustrates the shift in attention behind sonder: recognising that strangers have their own full lives, even when we know almost nothing about them.
