Artist Vs Poet - Leavin

I was walking with myself today
I couldn't help but think about your face
And I always regret cause I'm always forgetting what the rest of world looks like
I grab my guitar and I made some sound
Painted a picture and tried to leave you out
But your persistence led to obstruct my vision and I couldn't lay it down

I wasn't going to write a song
I wasn't going to write a song about you
I wasn't going to write a song about you leaving

I drink a fifth and started counting sheep
There were just as many as the days that you left me
Been marking it down, I never lose count
The bottles they don’t ever lie
So, I stumble to the keys and made some sound
Played it decent and then tried to shut you out
And I don’t know how but girl your melody came pouring out

I wasn't going to write a song
I wasn't going to write a song about you
I wasn't going to write a song about you
Leaving in the middle in the night through the back door
Leaving cause it’s all you’re ever doing anymore
Leaving cause you’re never going to find what you’re looking for
Leaving cause you want another song

I wasn't going to write a song
I wasn't going to write a song about you
I wasn't going to write a song about you leaving
(Cause it happens every time)

Could you show me where I went wrong?
Oh, could you tell me cause I’m lost without you
And I could put it in a song about you leaving
