A co-worker has a 15-year-old boy, and she says that in lockdown he went from being a sociable kid, a stellar student and an athlete to a morose creature who lies in bed all day scrolling his phone under the blanket.

You’ve got to pick up some skills that will help you find somebody to scroll with together later in life but this kind of lifestyle isn’t conducive to that.
