When you have a good heart, now matter where you are, help comes without asking, that is law of nature.. When I lived with my mother in law, I made sure I held her hand all the time, until I made sure she was comfortably seated.. When I drive my uncle and aunt ( in laws ) I make sure I drop them off at the entrance to the destination.. these are simple help that we should render without thinking, I think the gentleman who helped you near the escalator and in Kerala were good souls..
Rules are to be broken Mrs. Visa, I hope it does get broken for your sake..
