I went back to college in my 30s. Back in like 2016, when I was 34, I was approaching a classroom. I heard silence, and for a moment I thought I was late, and class had already started. Entering the room, I saw about 30 college freshman and sophomores, seated at 30 desks, all staring at their phones in silence. It freaked me out so much that to this day I go without my phone as much as possible.
