Acquaintance

When my son was little, my mom started collecting his outgrown clothes to give to strangers on the internet. She would meet these people through Buy Nothing, a project that had been created by two women from Bainbridge Island, Washington, not far from her home in Seattle. The mission of Buy Nothing, which had a local cult following, was to revive old-fashioned sharing among neighbors. People were organized by town or neighborhood into Facebook groups, where they could post what they needed, or no longer needed, and their neighbors would respond accordingly.

What made this different from Goodwill, Craigslist, or other freebie groups was that the people in your group always lived close by, and—because Buy Nothing was hosted on Facebook—everyone’s names and photos were visible, and messaging other members was as easy as texting. Pickups tended to happen at the front door, prompting face-to-face conversation. After a while, strangers became friendly acquaintances, their stoops integrated into your mental map of your town.
