Once

I once filled my room with chlorine gas as an experiment.

Very Green. Very Chokey.

I used to lie on the landing beneath the skylight, my duvet folded over me with just my head sticking out, and pretend to be a scallop.

This phase lasted a year or two. Saturdays mainly.

I blew-up a tree once.

The farm over the hill called as they'd seen the fireball.

And then once, in the holidays,

My brother and I built an island. 

It washed away with the tide,

As did childhood.
