Facebook has a way of showing people who their real friends are whenever misfortune strikes. That’s what Amy Pugh experienced when her husband walked out on her, their two children and three months of unpaid bills. She’d been using Facebook to organize her 20th high school reunion, tracking down many former classmates on the social network.

While she was planning the event in Michigan, her husband was also using Facebook — to coordinate a long-distance affair. Ten days after the reunion, he took off, possibly headed for Kansas. She kept quiet about it for two weeks, but some of the 250 friends who’d joined the reunion group on Facebook noticed that she seemed to have disappeared off the face of the earth.

They asked her if she was okay, and once she finally admitted what happened, she got the outpouring of support we’ve come to expect on the walls of the newly single and otherwise bereaved. The 250 friends that Amy had reached out to on Facebook created a page she couldn’t see and raised several thousand dollars for her bills, according to the Detroit Free Press. They also donated gift cards, diapers and hot meals.
