       There is this short story about a janitor at a fish factory (cold room), you know most of the times, people might just walk into a company or an establishment without reckoning the security personnel on duty, but, this story actually shook me, so to say. There was this lady who works in a cold room, any time she resumes duty in the morning, she greets the janitor, and, when she is about leaving, she does the same thing.  She does this virtually every day. Being the only worker who actually reckons with the janitor, it makes the janitor feel human as well, he feels valued as a human. So, there was this day she resumed duty, she did the same thing, made the janitor feel that same importance he had always felt, but, there was something unusual about that particular day; there was no one to say good night to him at 6 pm. He was certain something was wrong that evening because he actually got a good morning. He racked his brain for a while, and then, he decided to check all offices.
