Sacco boarded the plane. It was an 11-hour flight, so she slept. When the plane landed in Cape Town and was taxiing on the runway, she turned on her phone. Right away, she got a text from someone she hadn’t spoken to since high school: “I’m so sorry to see what’s happening.” Sacco looked at it, baffled.
Then another text: “You need to call me immediately.” It was from her best friend, Hannah. Then her phone exploded with more texts and alerts. And then it rang. It was Hannah. “You’re the No. 1 worldwide trend on Twitter right now,” she said.
