The financial crisis is reminding Americans of a lesson they first learned in childhood: Share and share alike. They are sharing or swapping tools and books, cars and handbags, time and talent.

The renewed desire to share shows up in a variety of examples: A car-sharing service has had a 70 percent membership increase since the crisis occurred. Some companies encouraged his employees to take vanpooling. Governments are putting bikes on the street for public use. How-to-swap Web sites are increasing quickly.

The economy reflects the way Americans have cut back, especially on daily items: Department store sales dropped 1.3 percent in June. People are not buying cars, and as a result, auto sales dropped 27.7 percent last month. They are not paying others to do what they can do themselves — Home Depot reports increased attendance at in-store do-it-yourself clinics. And although paint sales are down in general, according to Sherwin-Williams, individual consumers are still buying.

When Tom Burdett needed to cut some tiles at his home outside Annapolis, he refused to buy expensive tools. So he asked his neighbors and friends for help. Sure enough, someone had just what he needed. And when that friend needed help fixing a satellite dish, Burdett volunteered to help.

The sharing mind-set is not new to the American culture, but many Americans give it up when the nation changed from an agricultural society to an industrial one, said Rosemary Hornak, a psychology professor at Meredith College in Raleigh, N.C. They moved farther from their families and did not have time to connect with new neighbors because they worked so much, she said.

Neighborhood conversations tell more of the story as the movement grows organically (持续地) in communities across the Washington region and the nation. On one street in Arlington, for example, neighbors are collecting their separate money for mulch (覆盖料) and dividing it among themselves.
