Hmm, I think I’ve always been into it! I just didn’t know it growing up.
My favorite books had fairies, especially The Fairy Rebel. I reread that one constantly. TV shows with shrinking sequences always cheered me up to see. The Incredible Shrinking man horrified child-me beyond anything else, and once I recovered from the constant nightmares, I’d always be thinking up everything that could go wrong if I started shrinking like that.
Once I saw The Borrowers movie, they owned my heart.
Also, my mom likes a lot of this kind of stuff, so it’s not like it was discouraged. She’d cover our home in fairy homes and artwork for Tinkerbell. So it runs in the family!
