At school, social media can be a brutal barometer of popularity. “If you meet someone new and they ask for your Instagram and you only have 80 followers,” says Sharp, “they’re going to think: ‘You’re not that popular’, but if you have 2,000 followers they’re going to be like: ‘You’re the most popular person in school.’” Sharp quit social media at 13. “I’d rather not know what other people think of me.”
