The Rules of Reading

I want to complete some research into peoples pet hates about books, reading books, libraries, etc
This will all build up to a contemporary 10 commandments about books and reading...

My first list is created using online research, and the opinions of a few classmates.
I am also waiting on replies from a few book blogs / shops about their pet hates about how people interact with books.

Finger prints
Breaking the spine
Folding the corners book
Scuff marks
Not putting sleeves back on
Taking the front cover off
Leaving book marks in
Put them back in the wrong place
Leave the spine facing upwards
Write inside the books
Coffee stains
Water marks
Ruin the corners
Not finishing books
Flicking through pages only looking at pictures
Buying books and leaving it on the shelf
Watching the film instead of reading the book
Judging a book by its cover
Bending the cover
Creasing pages
Leave the book open
