The Love Pretzel

I was once in love,
A simple kind of joy
That occurred exclusively
Between a girl and boy.

Then another woman
Caught my vagrant eye,
And a triangle evolved
From what once was you and I.

But you had strayed as well,
And our love became a square.
I knew this would be easier
If we would clear the air.

As it so happened I fell in love
With only my original,
While you loved all three other corners
Although it was conditional,

And our other pair both fell in love
With us and with each other,
And I find we all are desired
By none other than my mother.

And thus my air-clearing venture
Cleared things up a lot
For it revealed our love pretzel,
Alexander’s loving knot.
