How do you do it?

How do you do it?
Make me feel this way
Writing stupid poems
Not knowing what to say

I should be thinking of him
Instead of you
But i want you more
I don't know what to do

Hes your best friend
It wouldn't be right
I don't want to be the one
To cause you two to fight.

So I'm gonna leave you both
To not cause you pain
Ill turn my back
And stagger down the lane
