Perfectly Lonely

A simple abstract from the lyrics by John Mayer:

I see friends around from time to time
When their ladies let them slip away
And when they ask me how I'm doing with mine
This is always what I say

Nothing to do
Nowhere to be
A simple little kind of free
Nothing to do
No one to be
Is it really hard to see

Why I'm perfectly lonely
'Cause I don't belong to anyone
Nobody belongs to me
