Where is my Best Friend???

Just read my friend's blog just now! I suddenly got a feeling... I feel sad! Don't know why?!?! How good if i got a closest and best friend, too?!?! Just one is enough! Just like them... Wahhh... How good will it be??? Hehee... Actually it's really hard for us to find a best friend who has lots of things are similar with us! (e.g. favourites and thinking) That's why I DON'T REALLY got a best friend ( ever got closest friend! I told her almost all my stuff cause I trust her! But don't think she is my best friend since this year... haizzz... ) but having a lot of close and good friends... Wish that I will also have my closest and best friend one day! Haizzz... *sad~~~ T.T But, can someone tell me how can a best friend be??? Only having lots of similar thing and thinking??? Never argued with each other before??? Know all bout each other stuff??? That's it??? ??? ??? Hrmmm... ... ..
