For 17-year-old Mary Amanuel, from London, it happened in Tesco. "We were in year 7," she remembers, "and my friend had made an Instagram account. As we were buying stuff, she was counting the amounts of likes she'd got on a post. 'Oooh, 40 likes. 42 likes.' I just thought: 'This is ridiculous.'"
Isabelle, an 18-year-old student from Bedfordshire who doesn't want to disclose her surname, turned against social media when her classmates became zombified. "Everyone switched off from conversation. It became: 'Can I have your number to text you?' Something got lost in terms of speaking face to face. And I thought: 'I don't really want to be swept up in that.'" For 15-year-old Emily Sharp, from Staines in Surrey, watching bullying online was the final straw. "It wasn't nice. That deterred me from using it."
It is widely believed that young people are hopelessly devoted to social media. Teenagers, according to this stereotype, tweet, gram, Snap and scroll. But for every young person hunched over a screen, there are others for whom social media no longer holds such an allure. These teens are turning their backs on the technology - and there are more of them than you might think.
Comment: Of course, you cannot have a convincing, heart-wrenching staged chemical attack if you don't sprinkle the scene with a few bodies of dead children.
The whole world has been warned now. If and when this happens, you know who to blame. You will also know that the Western bombardment to follow will be a naked, cynical and unjustified aggression.
