So, What is the Point?

I'm on my last set of Swingtown episodes. That makes me a little sad. I really have enjoyed this series.

In the 10th episode, when the daughter of the newly swinging couple runs away and gets picked up by an old lady for a ride.

The old lady is a font of wise words, not least of all, is this:

"Forever is not the point."

If it's not, what is?

And if it's not, is that such a bad thing?
