Define true friendship

Friendship......
A ship filled with friends,
but not filled with true friends
true friends.....

True friend means.....
A friend who is on my side,
A friend who makes me cry
out of happiness.
But does not let me be in sadness.

True friend means.....
A friend who takes me
to the correct path,
Because of which, I will always be sinking
in the river of love.

True friend means.....
A friend whom I don't just imagine,
 A friend whose image is in front of me
A friend who is my heart's key
A friend whose love towards me,
is as pure as melody.

True friend means.....
A friend who is the ink notations
of the pages of my life
A friend who is my life companion

True friend means......
A friend who is my eyes,
A friend who is my heart,
A friend who is my memory, and
A friend who is my guide.

Now I think, i can,
Define true friendship
