Yeah, then what?

As an atheist, this is the kind of story that drives me mad.  It seems a young boy was walking past a homeless man who was sleeping on the sidewalk. The boy approached the stranger, placed his hand on the man's body and began praying over him. For some reason or other the passerby who took this photo thought this was an amazing sight and it has since gone viral. Why? Prayer costs nothing. It achieves nothing. The kid didn't find the man a blanket, buy him a meal, recommend a shelter, give him ten bucks. No, he just stopped, kneeled, and mumbled a useless prayer. I'm sure he was a well-meaning young man, but this story is much ado about nothing.
