I felt very tied these days.During this period of final exam, two of my friends gave up the friendship between them.I did  my best to persuade them to make peace with each other, but no one understand me.I think I've done what I could do. Also would I have a feeling of failure. We have considered each other as members  of our family after the three years' campus life.Still now, they haven't talked to each other. When one comes across another one on the way to classroom, they would view her as a stranger.I really amazed at how they can give up such a  cherish friendship and how  they can  give up the beautiful time we have spent ever!
