"You're lying about reading chapter books as a 8-10 year old! No kid does that." - Extremely dumb take from someone who is probably illiterate.
A lot of books that are popular with children are chapter books and 200-300ish pages long. The Percy Jackson series, Little House on the Prairie, Harriet the Spy, Alice in Wonderland, The Rats of NIMH series, Diary of a Wimpy Kid, The Chronicles of Narnia series, Black Beauty, the Redwall series, the Artemis Fowl series, fuckin Animorphs.
Kids who get into the 100-200 page books like Goosebumps, pretty much everything Beverly Cleary has written, and books like Charlotte's Web [184 pages], start looking for longer books because they're entertained and enjoying themselves.
Sorry you were failed by the adults in your life and you never learned how to enjoy reading, but that's no reason to pretend that kids don't read. Maybe take an adult literacy course or something.
