Lo digo cantando

I'm not alone, I wish I was
'Cause then I'd know I was down because
I couldn't find a friend around
To love me like they do right now
Something's missing
And I don't know how to fix it
I don't know what it is

When Autumn comes, it doesn't ask
It just walks in where it left you last
You never know when it starts
Until there's fog inside the glass
around your summer house

Friends - check
Money - check
Well-slept - check
Opposite sex - check
Guitar - check
Microphone - check
Messages waiting on me when I come home - check

How come everything I think I need
Always comes with batteries?
What do you think it means?
How come everything I think I need...
