"That heron," I say, explaining away the mystery. "It’ll be that heron."
The next day, I am casting an eye over the newspaper in my parents' living room when, out of the corner of my eye, a flash of something colourful from the outside world captures my attention. I don’t have my glasses on, but I get up to peer out of the window, and can make out a goldfish flopping its way across the lawn.
I tear to the back door in pursuit, just catching sight of the errant fish heading into a shrub. I scamper across the lawn, and stick my head into the foliage. I am on the case.
"Whmf?" says the grass snake irritably, speaking with its mouth full as it pauses to observe me.
"Oh I’m sorry," I say. "I saw the… I thought it was… I didn’t realise you were…"
"Umhmm?" says the snake.
I realise our faces are inches apart, and I flee in terror.
