You Can’t Spot The Difference
Both a hose and a snake have similar characteristics when viewed in the dark: they are both long and smooth, and both expel something. If you want to water the garden the next time you decide to, necessarily make sure that you check the hose before you pick it up.
It is possible that the animal depicted in the picture is a snake that is currently experimenting with a new line of work, such as the one shown here. Always err on the side of caution rather than regret, and it will end up serving you better in the long run.
