'Take up 7 seats?': 40-year-old Karen lets kids take up too much space on crowded train, passenger gives Karen a tough time for the next 20 minutes

It may seem impolite to criticize someone else's parenting choice, but every once in a while, it's necessary… especially if other people are being impacted by said choices.

Here, we have a 40-year-old entitled Karen who, along with her two kids, was taking up seven entire seats on the train. This would not necessarily be an issue if it was a quiet, empty subway car. However, in this particular situation, there were more folks who were standing than sitting, including several elderly people who should have been given at least one of those seats. Since the Karen refused to teach her kids a valuable lesson on decent human behavior, the Redditor who was standing right in front of her decided to enact some petty revenge by making the subsequent 20-minute train ride a living nightmare for the Karen. By the time he left, the two made eye contact, and she became fully aware that all the so-called "accidental" bump-ins were actually done on purpose.
