Well,friendship can't be easily defined,the more you try to understand,the more you

want to know.Basically friends are the ones whom you can put your blind faith and

they will never betray you.They are always ready to help you in any situation whether  

it's a happy or a sad moment.They care for you,share everything with you,play with

you etc.But it,s not easy to find a true friend.I wanna tell one thing to claire as well

that it's not superficial,it's a reality you can still get friends like you describe.

the basic idea is that they have something in common, they can share things, secrets, good news,bad news,they can support each other.. there's a shoulder for one who is depressed or even crying, etc...
 but of course, these things are the superficial ones, coz it's like love,sometimes we can not explain what it exactly is. sometimes it's all the feeling things, we are unable to expound. too mysterious. and also, friends are not counted in quantity, but quality..not all the people we know are our friends.

people are sometimes confused about friendship when they are betrayed or something..but that's life..
have to say, mostly, we can only depend on ourselves..
