Thanks all of you for sharing your thinking in here.
To me: I love my family, my friends....so many but I always think about my grandmother firstly when I feel happy or  unhappy. She is my life. :) 

The most important person in my life is changing all the time. He or she is the person that is closest to me in the present moment. Is the person I am talking to, is my neighbor, my child, my college, my girlfriend and so on.

 The most important person in my life, is no other than my 'MOM' <img alt="" src="http://www.italki.com/fckeditor/editor/images/smiley/msn/wink_smile.gif" /> Actually, I can't really say that she's the only most important person. My whole family, they're all really important to me. They're the reason why I breath, work, and live.
