For as long as I've been alive my Mother has worked the night shift at Quest Diagnostics. She's a lab tech and runs blood samples from 9pm to 6am. All I knew about her job was that she worked at night and handled a lot of blood.
My Mother also has a slight allergy to vitamin D and because the sun's rays give off a great deal of vitamin D, she breaks out whenever she's in the sun too long. Effectively, she's "allergic" to the sun.
In 4th grade, I started to put these pieces together...allergic to the sun? Works at night? Handles blood samples? Obviously, my Mother was a vampire. I scared the poop out of some of my friends who were over at my house on a weekend telling them this about my Mom.
