Last Saturday, I went on journey by train. There were such many passengers that not everyone could get a seat. Many people had to stand, which was really tired. I had a reserved seat so I could sit comfortable. In front of my seat is a woman with two little kids. With the kid squeezing into their single seat, she had to stand up all the way. So I moved a bit but shared my seat with her. The woman felt very grateful to my selflessness. Seeing her beautiful smile, I also smiled. Share increased happiness!
