Twice now I've been out in my yard with my younger brothers catching butterflies for them, and one butterfly will fly around the cage while I try to get one in, and then fly in before I close it. And the first time it happened, when I released them, one (I believe it to be the same that flew in) flew around me and my brothers playfully, and even landed on my finger for a moment. Could these be fairies in disguise, or just random coincidences?
Ask yourself, how in the world could fairies "disguise" themselves into a butterfly? Escpecally since you have no proof that they exist. It's just a butterfly, they like to have fun too you know! It is not a coincidence at all, really. Just a playful butterfly, like all other lifeforms are.
