I participated in a laughing circle with a group of friends. One of us had read an article about the growing popularity of laughing circles in India, so she sugegsted we do it, and we did. At first I thought it felt forced and fake to be standing in a circle with others laughing at nothing, but after a few minutes the contagion of laughter took over and we began laughing naturally until we wore ourselves out from laughter. It was an interesting experience.
