What are friends for...

What's wrong with me....arrgh...exams are juz 9 days away & I am down here writing this blog...sometimes it really makes me wonder what is the definition of friends. Does friends=someone you can use of and discard them when they have outlived their usefulness or someone you take for granted? I really wish to know the definition myself. Have been seeing friends whom I have known for a decade falling out with another friend for some reasons which I don't wish to know also because I have experienced it myself even till today. Over a couple of months, it has made me realised that those who can live with your good & bad points and who are close to your heart are worth treasuring and only time will tell who are your true friends. With this it makes me more determined to find myself a person whom I can truthly share my life with because she will be the one who can live with my good & bad points. I hope that she will come into my life one day...Sounds desperate...
