Again

Again, this couldn't happen again.
This is that once-in-a-lifetime, this is the thrill divine.
What's more, this never happened before,
Though I have prayed for a lifetime,
That such as you would suddenly be mine
Mine to hold as I'm holding you now, and yet, never so near,
Mine to have when the now and the here disappear,
What matters, dear, for when this doesn't happen again.
We'll have this moment forever, but never, never again.
