One of my previous workplaces was located very close to Tabán in Budapest and sometimes I walked a fair distance to clear my head. There was a location during the walk where I regularly saw moss and small snails so I decided to take my camera with me a few times. I was fortunate enough to come across this small snail, hiding. When you're just a few centimeters from them they are much faster than from a distance :)
