They gather to do the silly and inane activities from childhood that most adults think themselves too mature to take part in, like the pillow fights. I am fascinated by this. What a great stress reliever it must be to meet up with strangers in a public place and spontaneously have a pillow fight, or water balloon fight, or dance to music from the Broadway show Grease. The gatherings last until they are over, with no time constraints on the fun. It’s over when everyone goes on their way.
In the United States, we need some stress relief. We need to have fun. We need to laugh. I can’t think of a better way. I found the Pillow Fight Club for those of you who want to get in a few good shots with a downy dream catcher. I also found this article about flash mobs in Austin, TX.
