If you havent mentioned phobias, and stopped before the fifth stanza, this would’ve been really dark!! Anyways this is very clever, love it :)

. . . Snakes?!
Don't worry, I went through a really bad patch a couple of years back of bring petrified of snakes. My late great grandmother used to have a huge garden with a small wood at the bottom of it. I used to be so scared of being bitten by snakes that I'd never go down there and play with my brothers - up until I decided that - since I'd never actually seen a snake in the wood - I might as well get on with it. I've never worried about snakes since.
I have a ridiculous amount of fully fledged phobias, not just silly fears. Some of them sound so silly, too! Hemophobia, the fear of blood, claustrophobia, the fear of tight spaces, arachnophobia, the fear of spiders, and I have many others that I don't know the name of. The most stupid phobia of all is the phobia of our hoover. It just sounds embarrassing! But I'm terrified of the thing and I always worry I'll somehow get caught in it and hurt.
So. a fear of snakes isn't that bad! X

there is something about snakes that make them something to fear. Like your poem depicts, but without saying, they look and move in ways that are sinister. Nothing that looks like that can be good. As for the phobia they really can and do induce a heart rate that can deem the person unconscious.

Nice write, Em. xx
