many of them describing that word as :

friend is someone who likes you to be ..
friend is someone who can makes you to be yourself ..
friend is someone who appreciates your kindness , and doesn't have an objection with your weakness ..

with friend you can share so many laugh , happiness , secret , thought , or may even sadness ..

just like that ?
NO !
that's just the outer casing .

friend has more complicated words to describe .

as a matter of fact , we need friend to supports us keep walking in our right way , keep struggling to pick our obsession , and running together to achieve our destination ..

but when it runs away from the truly meaning , do we can still call it as friend ?
