When my little sister was about 4 years old, my mom was explaining pregnancy to her. My mom told her about the baby growing inside the mother, how it starts as an egg and grows into a person and then she mentioned that it grew in a sac filled with water. My little sister got a horrified look on her face and my mom, obviously worried, asked her "What's wrong?" and my sister said, "but aren't there sharks and fishes in there?"
