Friendship

I have been planning for a long time to write about friendship.
I initially planned to write it last month.
But I postponed it until now.

Last night,
I attended to a talk.
The talk is about relationship between humans.

Well,
I enjoyed the talk.
It is really a great talk.


For some people,
friends are just their tools.

But for some people,
they are ready to sacrifice for their friends.

So....

What is 'FRIEND' actually?

Who are friends?

Do we all need friends?
