Dear Cienna,

Sometimes when I buy books from used bookstores, I feel bad, especially if they're from small presses. Authors get royalties, however small, on each book sold new in bookstores. They get bupkis from used book sales. Maybe this doesn't matter so much for James Patterson, but when I buy a used copy of an indie title with a tiny print run, that sale could have gone a long way toward benefitting an author, or at least helping their self-esteem. Am I being too sensitive? Or should I only buy copies of bestsellers in used bookstores from now on?

Dear Cienna,

I like readings. The one problem is I feel guilty if I go to a reading and don’t buy the book. What’s the etiquette here? Is there a rule of thumb? There are so many variations to this theme: sometimes you like the book and will considering buying it later; sometimes after a reading you decide you don’t like the book; sometimes you like the book but it’s too expensive.

I keep coming up with other examples from my life. Is it okay to tell an author you’ll get their book from the library? And what if the author at the reading is your friend?

My anxiety grows by the minute, Cienna. Only you can help me.

Effie, Mountlake

Dear Effie and Ingrid,

Guilt should be reserved for religion and select situations that deserve it, like telling a Girl Scout you have a tumor just so she will give you a free box of Thin Mints. To answer your questions:

• Buying any and all books from used bookstores is fine. Authors also get nothing when you lend a book to a friend or check a book out from the library. Think of it this way: If those books weren't being recirculated, they'd be rotting in basements, used as coasters in bars or burned by people like me.

• First and foremost, writers are thrilled to have butts in seats at readings. You are basically doing a very specific community service for one very grateful individual when you attend them. That said, you shouldn't ever feel obligated to buy a book. If your misplaced guilt overwhelms you, however, there is a compromise: When I attend readings and the book doesn't grab me but I really liked the author, I try to think of a senile aunt or friendly shut-in who might enjoy its content and buy it for them as a gift.

• That said, yes, you are absolutely required to buy your friends' books if they are published authors. It is a $20 investment. If you are not willing to invest $20 in friendship, you do not deserve to have friends.

Finally, I would encourage you both to ruminate on the nature of guilt. I am concerned, based on the tenor of your questions, that neither of you has truly experienced this proverbial shit stain in the rich tapestry of human emotions. Guilt, when done right, should feel like running a coal mine marathon: You should be sweating more than normal and overwhelmed by a claustrophobic sense of hopelessness.

I recommend that you explore this feeling, either by looking someone in your life in the eye while you tell them that you love them and then taking it back 10 minutes later, or by actually running a coal mine marathon. Then you both will be better equipped to tackle slightly uncomfortable social situations, like how to conduct yourself at a book reading, in the future.

Kisses,

Cienna
