"'Have to' is a good master."

Necessity is the mother of all invention, eh? But it could be seen in another way too. That it's still a master, that you let necessities control your life, rather than being the master and realizing nothing is "a must."

Here's a quote that speaks for the other side of the coin:
"Argue for your limitations, and sure enough, they're yours." - Richard Bach.

It's interesting you speak of the poem reminding you of something that goes beyond it, because in it, there is no more strength without the other person.
But I guess in art, what is not said is often as important, and certainly what it makes us think of.

Thank you for the comment Moe :)
