My mom's ship logic

[endlessrain_x]

So my mom was one of those "Harry Potter is evil" Christians when I finally convinced her to read the first book so that even if she were to keep thinking so she could at least maybe find something to base it off of rather than what other religious crazies say who've never read it. She's now on the fifth book and a while back she basically said she ships Mrs. Norris and Crookshanks.
What is happening.
