Because she’s terrible. ._. From the very beginning she’s cruel, selfish, mean-spirited, and the poster child for the stereotypical “mean girl/queen bee”. Although the show did a decent job at giving her dimension, as someone who was heavily bullied in elementary school, she reminds me of a particular person I knew in school when I was younger. She had the same fake cheery attitude as Heather and treated me like Heather treated Beth before eventually backstabbing me and spreading vicious lies about me through school.

So whenever I see Heather, I just cringe because she’s nothing more than a bully in my eyes, and I don’t like that in any character, fictional or otherwise.
