Please Excuse My Rhyme

I'm afraid that I don't understand
It's simple, she replied
It really only all adds up
When looked at from inside
I've tried, he said
It still remains that 1 plus 1 is two
And then we talk and you
Insist that yellow's really blue

What's right is right
And left and such
Do I really have to say?
I thought that we were grown up
But all you do is play
The word games that you love so much
Were charming at the start
But now they've simply gotten old
And torn us apart.

There was no us, he countered
That's where your logic fails
There wasn't any part of this
That wasn't fairy tales.
In this you're right, the words we said
Cannot be erased
So now your words became your wish
And you have been replaced.

*Disclaimer: Please excuse the simple rhyming. It's typically not my style. But sometimes stuff happens and you have to write it down.
