Lyrics: Sean Lennon. Friendly Fire. On Again, Off Again.

And just as the sun sets
just as we will forget these precious moments
when another day is through
And just as the moon knows
we cannot always glow through every evening
some days you will find me sleeping

Cause I'm on again
and off again
I never told you
I never will
Cause I'm on again
and off again
If I can't hold you
somebody will

Love is like the ocean
Forever in motion, forever changing
Never twice the same
You may miss me one day
You may have wished you hadn't stayed
You may forget me
You may never let me go

Cause it's on again
and off again
I never told you
I never will
Cause it's on again
and off again
If I can't hold you
somebody will
