Update: Hooray, I'm famous – BoingBoing.net used my link :). Well, acknowledged that I pointed out the video link. Close enough :).
When I first heard about this in passing I didn't think much of it. I didn't realize that there is video. This is the incident you may have heard of where a small boy climbed under the ropes in a Kansas train station and danced all over a Buddhist sand mandala that they had been working on for days. The video shows the entire event, and I have to admit that I did look at the progress bar to see when it would mercifully be over.
Perhaps the most annoying part is not the child – I mean, come on, he's maybe 2 years old? — it's the mother. Not only does she leave the child completely out of her site for close to 2 minutes (in a train station?!), but when she finally comes to collect him, she never even stops to look at the damage he's caused, and makes no effort to make amends or even to acknowledge fault. She just walks away. Not sure whether to call her a bad mother or just a bad person in general. Wherever you are, lady, I hope you get reincarnated as a centipede. And I stole that joke from NPR's Wait Wait, Don't Tell Me. The best part of the story, of course, is the quote from the monks who simply said, "No problem" and started over.
