This song has been one I can't get enough of lately. 

It's "Forgive Me" by Missy Higgins:

Oh my son look at what I've done

But I am learning still

Learning still

Know that I am learning still

And oh my wife you are my life

And I am burning still

Burning still

Know that I am burning for you still

And all, all of my light is for you

And home, home's anywhere you are too

So take this one fallen man on his knees

Saying please forgive me

Oh my God how you make it hard

Not to pick the apple

Pick the apple

And Lord I long to give it back

And I was on shaky land

Lost and unsure I opened my hand

And she held it like sinking sand

And all, all, all of my light is for you

And home, home's anywhere you are too

So take this one fallen man on his knees

Saying please

All, all, all of my light is for you

And home, home's anywhere you are too

So take this one fallen man on his knees 

Saying please forgive me

Forgive me

Forgive me
