Cartoon drawings on book covers — for some reason I associate them with supermarket trash
food spills on pages (although I am sometimes guilty of this)
ripped pages/book covers (I like my book in pristine condition)
cutesy animal stories (no Black Beauty for me)
an “I’m setting this book up for a series/sequel” ending
Goosebump cliffhangers, I don’t know if anyone read R.L. Stine’s Goosebump series in the 90s but his chapters would end with a door creaking open only for it to be a cat. Even at the age of ten it annoyed me.
Infidelity — I still read books that include this topic but I think its gross and over done
Absentee Parent — This is an extremely prevalent theme in young adult books (and even tv shows) its an invitation for “girls gone wild” and the consistency of this theme gets a little old.
