when passing the bus station on my way home, I found out a little girl alone crying. Obviously, she way losing, looking for her mother. I came up and asked her why. When asked where her mother was, she just shook head and kept crying. Then I took her to the station broadcasting room for a help.” Anyone who lost a child please come to our broadcasting room…” which was soon heard again and again. Minutes later, a worrying mother came. The girl ran to her mother happy, tears still in eyes. The mother was very thankful and asked for my name. With smile, I answered,” I’m only a League Member.” I have just done that a League member should do. It’s my duty.”
