The part about the lima beans reminds me of this one children’s book called A Bad Case of Stripes.
Basically this girl likes lima beans, but pretends to dislike them, and the world punishes her by making her go through all sorts of unsettling body horror for a children’s book.
I have a theory/headcanon that “Twinky” is actually Calvin’s surname, since I noticed it’s common for bullies in fiction to refer to their victims by their last name.
As an Alaskan, I’m used to it getting dark during the winter.
Summer is my least favorite time of year because it’s so hard to sleep when it’s bright out.
