This is the story of one of my friends. While returning from the work, he saw that some people, who were traveling in the train were giggling at a woman sitting nearby. In the initial, he didn’t get why they were actually laughing. Even that woman was uncomfortable and was not sure why they were laughing. But, soon friend realized that the woman seating nearby has the big torn seam of cloth nearby her back (For Example, not exactly like this) He could have directly asked the woman to shift the bag from right to left. But as she was unknown to him, so publicly he avoided saying anything because she was already uncomfortable. Then, he just took out his phone and typed something and shown the screen to the woman. The presence of mind he showed, has made the woman comfortable. Source : Aditya Pratap Singh
