He Calls a Mansion, Not a House, but a Tomb

You never know what you'd find on a city bus. Frank Iero had been writing novels for years and had always written the best when he experienced what he wrote. Or at least tried to. He tends to observe life on Earth and everyday life.
He finds it interesting to watch life pass you by each day. How millions of people live their own lives, and no one really knows it.
People focus on their own lives and that's it. No one would see a man at the other end of the bus and know what he's going through in his life at the moment.
Frank notices things and is fascinated by observing life. Until, however, he takes a detour of his usual route and follows an eye-catcher off the bus.
