Ironic ending
The man was also on his phone after sitting on the kid, which is probably the most incredible part of this entire scenario. As a result, it appears that the reason the kid didn’t move was that he was so engrossed in whatever it was he was doing on his phone.
However, before long he was followed by another male who pulled out his phone and disappeared into the realm of technology. It’s one thing or the other; either way, it’s hilarious.
