Why are you my friend?

I leave and I do not tell you why
I break your heart and tears run dry
I do not yield when you cry for help
I do not wince when you cut yourself
When you look my way I do not bend
My dear, why do you call me a friend?

They say a friend is a gift of god
Well if that is true then i do not applaud
This most incredible yet undeserving gift
It bows me down rather than uplift
It is a wound on the heart to mend
My dear, why do you call me a friend?

Its a lesson that I need to learn
The mysteries of this gift I must discern
What does it mean to have a friend
Be there for you at every bend
Even though I do not give the same
I get the gifts and the fame
When I do not give or even lend
My dear, why are you my friend?
