He Was Right
The mysterious guy had every right to sit down on a train when a seat was available, even if it happened to be on a child’s legs. It wasn’t just about sitting down. This man wanted to teach the boy a lesson since his mother couldn’t be bothered to do it.
Blame Game
The story then gets crazier. That boy’s mom had no idea that the man was sitting on his legs. Once they were freed, she quickly realized that they’d missed their stop and blamed her son for doing it on purpose.
