Flash Mobs

Maybe I was a bit too judgmental about the subject of flash mobs. They seem harmless enough. I was just irked by the one where the people who were blocking other people from catching their trains at Grand Central Station. It just seems to me a little selfish to impede on others for your own enjoyment. What if a person missed a train because they could not get through in time? I know that there is a lot of would of's and could of's in that question, but it is entirely possible. It just seems like life is hard enough as is without having to deal with another person's shenanigans, but maybe a person was having an awful day and that mob provided a sense of humor that was not there before. That could the case as well. So am I to judge other people's actions? Maybe I'm a little jealous that those people are able live so carefree? Either way, I always say to each their own, whatever makes you happy as long as it is not at the expense of other people. So I guess consummation I should not be so quick to judge.
