Life has turn back to normal again. That was what I always wanted since middle high school, peaceful and quiet. However, I am changing a lot.  Anyone who ever knows me would not deny it. Acctually, the chaos and uncertainties in life used to be a disaster to me, I can't even bear to think about it. Not even today. To tell you the truth, quite weird. I do know that. It is not good to introspect yourself too often, I think, "participate in things' is more important than just thinking about it. You have to do it. I realize this recently. Hope it won't be too late.
