He and I....

We  fight about the menu, we fight about the car
We fight, therefore we are.
He likes order in the garden, I like order in my file
But, together, we've travelled many a mile!
Numbers speak to him, words speak to me
Disparity - is this the key?
He says aqua and I say green
Over colours too we vent spleen,
Our daughter is like him, our son, like me
Together we are one happy family!!
