Helpless man

One day my friend and I were walking in the evening.We walked around three to four kilometers from home to a nearby river,I had a voice of a person crying for help. When I told my friend I had a voice but she ignred telling me that I was day dreaming.
        Since the yopungest among them, I had nothing to say but only to keep quite and keep my mouth shut
