Trapped in a Parallel Universe

Two situations, one put it reverse,

I’m trying to figure out which is worse.

What is or wasn’t?

Does or doesn’t?

Is it ripe or just not quite rotten?

But the hardest challenge is not which is worse,

it’s finding which one came first.

For what is the product of the reverse reversed?

What about the cursed uncursed?

Maybe this doesn’t make much sense,

But you’ve got to think in the past’s present tense.

For this happened to another me...technically,

but perhaps slightly differently.
