I'm a leaf Lyrics

I'm a leaf on a tree
And it's time for you, let go of me
I'm about to turn orange and brown after that
Will you promise not to be sad

I have done all I could
And I've done all I should
I loved being near you, that I want you to know
But it's time for me to go

You have taught me to smile
Even if I should drift a while
I'll get back to the ground and I'll make you see
A new tree will come of me
