Am I really a “rotten, snotty, evil bitch” if I’d rather not lend out my books?

Honestly, it has nothing to do with the fact that my sister wants to borrow the book. It’s the fact that any time I lend any book to anyone, I either never get it back or it comes back a big mess.

And now my mom has decided I’m a rotten, snotty, evil bitch and I don’t deserve the Hanukkah present she bought me and hasn’t given to me yet.

What the hell did I do incorrectly?

I even explained to my sister nicely why I’d rather not lend her the books.
