I start to understand that no anybody are happy even you see their smile on face. Sometimes, a talkative person has agony even he or she can make you laugh.

I start to know that life is a cruel machine, no matter how sad you feel it still forward day by day. I feel i am still chirdish, my mood will be affected by a little difficulty,i will feel awful when i encounter some setback. I should be stronger and brave, as the life is that. You will be striked down if you are too weak.
