Uptight.

We are undercover passion on the run
Chasing love up against the sun
We are strangers by day, lovers by night
Knowing it's so wrong, but feeling so right

I've got something that I must tell
Last night someone rang our doorbell
And it was not you my part-time lover

And then a man called our exchange
But didn't want to leave his name
I guess that two can play the game
Of part-time lovers
You and me, part-time lovers
But, she and he, part-time lovers

Live in the moment he tells me. Live for the now her persists.

But is the me in the now the me that would do this kind of thing?

I don't know.
