I have seen people in the same room texting each other.
Channel surfing the other night, I came across a show titled "1000 Ways to Die" (or close). With nothing of interest on TV, I tuned in to see a segment about a guy in a pickup driving while texting his girlfriend, who'd already arrived at their destination. She was walking through the parking lot, texting him regarding his whereabouts. They kept texting back-and-forth him driving, she walking, until he ran her over with the truck, killing her.
I turned off the TV.
