Impossible is Nothing

I am a graduate student today but I think I could not have survived this much if someone special in my life would not have sacrificed the most favorite thing of his life. The special person I am going to talk about is my father. Let me come from the first scene I remember. In my very mere age my father used to work as a night guard in the embassy of Islamic Republic of Iran which is situated in Dhaka. For which he always was the latest person to return in our locality. During this profession he went through great joyful and comfortable life.
