When I was maybe six, I thought that "Sea Monkeys" (the little shrimps you could whip up as pets) really were little people- as depicted on the packages I saw at the store. I remember thinking how horrible it was that you could buy these tiny little people who were then totally at your mercy- what if some stupid kid didn't take good care of them?
Of course, none of that stopped me from wishing I had some of my own. I asked my mom for some and when she told me they weren't really people but were only boring little shrimps I didn't believe her. I thought she was just lying because she was too cheap to buy me some.
