Time travel’s a reality,

We do it every day;

A function of causality,

But only goes one way.

 

That’s how it always seems to me,

Despite what Einstein said;

I’ll never make the speed of light

To turn time on its head.

 

So though time’s only linear

And no-one has the knack

Life might be so much happier

If some could travel back

 

I’d get to whisper in my ear

When acting like a brat,

And say with foreknowledge clear,

For Pete’s sake, don’t do that!

 

But then I think what might transpire

If history was changed;

My future self may not be here,

‘Cause life was re-arranged.

 

A temporal anomaly

Would not be too much fun;

It’s safer just to wait and see

That what I did is done!
