When I was about three or four, I used to think that babies came from "the baby store." Hey, groceries came from a grocery store, so why not?
I thought that babies would sleep on little cots that were lined up all around the 'store', and prospective parents would come in and choose a baby or two. I also remember believing ardently that, when I had been purchased from the baby store, I was wearing my pink "Martin Guitars" shirt, even though my dad had bought that for me when I was two.
I remember proudly telling my parents that I knew where babies came from, and they nervously asked me where I thought babies came from. When I told them the "baby store" they both burst out laughing.
