Harridan 10: The Constantly Assailed
One of the most annoying things I've ever seen in the strip would have to be when Mike asked Elly if he could have junk food. In reality, he probably referred to the desired menu item by a trade name but you just know that Mommy Dimmest heard the words junk food and will always remember things that way. This is owing to her living in a horrible world filled with things and people who want to ruin her.
This not only explains her dread of the world outside of her suburban redoubt, it tells us why she lives in fear of dangerous outfits and dangerous information. She sees anything that challenges her reign of tedium and safety as being another nail in the cross she never actually had to bear.
