A childhood belief about fairies

On the summer weekends, my mum and dad would take me and my little sister on walks in the woods. Dad used to tell us that the wood fairies left Opal Fruits on the stones on the bridge. So we would look on one side, but there werent any, so Dad told us to look on the other side, (while he put some on the first side) and so we would swap sides again and miraculously find Opal Fruits! We took ages, years to twig what was up.
There were never any sweets in winter, because the fairies were hibernating.
Then one summer there werent any sweets at all, and Dad told us the fairies had all moved to Florida and werent coming back.
