digits in the negatives

We are not simply strangers with memories as everybody says,

Nor are we acquaintances or friends of a friend.

We are not lovers; I am not sure if we were. 

We are no longer classmates and I’m glad about that.

Having given some thought, I would place us on the line of regret.

There is no way of knowing, though I can guess, that you desperately wish

We had never met.
