I don't think so. Let's go back to that girl who texts 250 times a day. The truth is, she was an extreme case I cherry-picked to startle you – because when I interviewed her, she was in a group of friends with a much wider range of experiences. Two others said they text only 10 times a day. One was a Facebook refusenik ("I'm all Instagram, pictures of what I'm doing in the city, with my friends. We're visual people"). A few were devotees of Snapchat, the app that lets you send a picture or text that, like a cold-war communiqué, is destroyed after one viewing. One had a phone filled with charmingly goofy emoticons, another disapproved: "I'm a skilled writer," she told me. "People sometimes misunderstand tone, so you have to be precise." As it turns out, the diversity of use in this group of friends is confirmed by research. Fewer than 20% of kids send more than 200 texts a day; 31% send barely 20 or fewer.
