I saw a lightning strike

It was close by

In the clouds

They were soft grey innocent like a

Tabula rasa

And the sky wrote on them

One bolt of bright lightning

Moving swiftly from right to left

There was a sound

Like a snake or a flame

A hiss

Exactly simultaneous with

The appearance of the lightning

Three seconds later

I heard the thunder

What did I hear

When I saw the lightning?
