I used to believe that fairies were real and that they hid when they saw humans coming.
I would look under leaves and in flowers to find them, but I never saw even a single sparkle. :-(
In the end, I figured out that they were a made-up concept, but at least we have bumblebees, ladybugs, butterflies and dragonflies, which are honestly just as cool as fairies.
