I think it is a piece of paper which has a signature of my brother on it.I got it two weeks ago before we are seperated into two worlds.Virtually,it is provided by myself,and my brother just as my request signed on it.I still remember that it was a normal but significance night that he wrote his name down on this paper in our farewell.He saie he would not see me for a long period,and it does true.We totally have been out of touch for almost one year.Now I find it is unbearable to living without him,but when I saw that meaningful piece of paper,there is something warm appearing in my mind.I regard it as part of my life,and the source of courage.Maybe just because of the unrealized love.Since,I have already lost my dearest brother,anyhow I cannot lose the nostalgic paper.
