A childhood belief about fairies

When I was five I had a best friend who used to come over my house a lot. . We used to use a big black tree pot (with dirt in it) and make a "fairy farm". We put flowers and made furniture in there, and sometimes we would sleep out in a tent (in the backyard) and check if the fairies had come yet. In the morning there would be silver glitter all over the pot and the crumbs we left out were gone. We used to thing it was the fairies, until a few years later I guessed when the silver glitter run out!
