Losse remembers when she and other Facebook employees were driving to the Coachella music festival, a six-hour drive that she assumed would be filled with music and chitchat. "This was a different time and a different kind of road trip," she wrote. "As we drove into the darkness of the I-5, computers and gadgets started to come out of custom-made Facebook messenger bags and were turned on. While I was resting against the headrest in the backseat, trying to sleep, I saw the telltale glow through my eyelids of the laptop screen bobbing in front of me. 'Nooo, not again, not here,' I thought. I understood the constant presence of photos and video at parties but in the car? While I was sleeping?"
