This song made me cry once again. I did not control myself and shed tears. I listened to the song for many times.
I would request all of you to share the link of the video with your friends. Do share it on twitter, facebook and the like.
Please keep a copy of the video near you and listen from time to time as we cannot afford forgetting these great and brave kids who sacrificed their lives for Pakistan.
