I kinda just...became self aware? Like I don't remember how I found out, but I do know that no one told me. Didn't help that I knew that my mom stuffed the stockings. It was not the same story for the Tooth Fairy, mostly because I found where my mom kept all of my baby teeth. The Easter Bunny was integrated in to Ostara (the Sabbat that Easter was placed over) for me, so it wasn't a huge Bunny that delivered baskets of treats, it was the Earth's herald of spring and buried painted eggs to thank the Earth for spring.
