As I sketch it through the window of the house next door, I notice that attached to the outside of the glass there is an object the size of a very small pea.
I bring it in to sketch and, to my surprise, it springs to life. It is a tiny snail, a perfect miniature, which stretches out its eye stalks and crawls around on my sketchbook, crossing the drawing several times as I draw, but luckily leaving only the faintest of slime trails.
Against the light of the window it is translucent, but its shell does seem to have the start of a streaky pattern. Perhaps this is a young Brown-lipped Snail, the most conspicuous of snails alongside footpaths and in some gardens.
