In paragraph 5, the author quotes Athena: "'What does that feel like, when you're trying to talk to somebody face-to-face and they're not looking at you?' I asked. 'It kind of hurts,' she said. 'It hurts. I know my parents' generation didn't do that. I could be talking about something super important to me, and they wouldn't even be listening.'" The phrase "didn't do that" refers to the behavior described immediately before: "talking about something super important to me, and they wouldn't even be listening," which is a lack of attentive listening.
