Unconsciously i m 21 year old now..many things changed during my life now. some of my friend will graduate soon, some of them had already graduated and start working, whereas me, will graduate after 3 years. what i m thinking now is what will be happened after 3 years between me and my friends. R they married? R they gift birth? or not contact any more? what will my life be after 3 years? i m 24 year old! i want to know what is my future?!
