A childhood belief about imaginary friends

At about the age of six, I believed that two little penguins lived under the pews in my family's church. I saw them peeking out at me from beneath the pew in front of us on quite a few occasions when we were kneeling and praying. Sometimes I whispered quietly to them to see if they'd play with me, but they never did anything but sit there and stare, so I eventually gave that up and just watched them.

Years later I realized that the "penguins" had actually been the high-heeled shoes of the woman sitting in front of me. They were black on the top and white on the bottom, so when the woman knelt and the heels were sticking out, they looked like little tuxedoed birds! Good thing I never tried to touch them or told anyone about my little friends.
