Paris residents warmed the Internet's collective heart Friday night by using the hashtag #PorteOuverte, or "open door," to offer shelter to strangers left stranded after at least six deadly attacks sent the city into chaos. A few hours later, people across the U.S. returned the favor with a hashtag of their own: #StrandedinUS.
The hashtag #StrandedinUS began trending overnight Friday into Saturday with offers from Americans willing to help Parisians having trouble making their way back home due to airline cancellations or delays. People offered up beds, couches and hot meals to French nationals in need.
Those having trouble making their way back to France were also encouraged to use the hashtag to ask for help.
