Teenage Friendship

Every life which lives/takes breath on earth has a friend.

but every friendship doesnot longers more than a certain time.

mostly because of misunderstandings

but  on my view it is not cause of misunderstanding but not proper understanding 

i have studied somwhere that friends which you make below 18 will be with you life long and 

the friends whom you meet after 18 are just for the professsional purpose.

so nothing to say im not that much expeienced im all alone
