Back when I was five or six, my best friend and I were hanging out on the playground. Her older sister was showing off her new yo-yo, and we were immensly jealous. So, we created our own imaginary friends. We each had a chipmunk, and it could turn into a yo-yo!
We had hours of fun playing with them. Then we started creating more and more. Eventually, some other kids asked us what we were doing.
I told them we had 'Invisible Animals'. They wanted some too. So I handed them an egg (invisible, of course), and said that if they held it close to their heart, it would hatch into their own animal!
God, I was a strange child. O.O
