The truth of a lie

I wanted to hide a truth.
I told a lie.
No one thought it was true.
I know I have hidden my truth.
Like the green leaves in daylight,
Everyone knew I hid something,
But no one dared to ask,
For they knew it was a lie.
One day I revealed the green.
They called it yellow.
My heart was broken.
I flew down the tree,
I thought I would be a lie again,
That I would fly like a bird.
But I am the truth,
I was just a fallen leaf.
