This reminds me of people who think it’s funny to drive off when a friend is trying to open the door to get in the car. Then they stop and drive off again, laughing hysterically. These are not friends. They’re not even funny. I prefer humour that doesn’t make others genuinely feel bad or that is completely one-sided. I like the confessional prank a lot more, because he also got in trouble (totally worth it I suspect).
