1. A disappointing ending that ruins an otherwise perfectly good book.
(Why do authors do this?)
2. Over 100 holds on a book I want to read RIGHT NOW.
(Patience isn't my strong suit.)
3. Impossibly hard-to-get, out-of-print books that are too expensive to buy just to read once.
4. Not enough shelves!
(Because owning too many books couldn't possibly be the problem.)
5. My library still closed for renovations!
(It's been four months, people. Finish already!)
What frustrates you?
