Over the summer, I was reading a newspaper at a subway station near my apartment when my blood ran cold. I felt creeped out when I read that hours before, in the very station where I was waiting, a few feet from where I sat, a man injured an MTA employee and a random commuter with a chainsaw. It was an attempted New York Chainsaw Massacre.

Today, I read this about a good Samaritan at another familiar subway station. It was much better news.
