1) The Father
He is playing a father's role when he is holding your hand and helping you to take the first step of your life as a child. He ia playing a father when he let you enjoy a horse ride on his back. He is a father when he holds your hand firmly in his own hand and let you feel the warmth of his hand.
2) The Friend
He is playing a friend when he is playing cricket with you or when he is running madly in the lawn. When he is breaking the window glasses of the neighbors with you at that very moment he is a friend to you. When he clings to you in your bad days he is your friend.
