Last year, it was a few months before my students found out about my book.
This year, it took two days.
I’ve already had this conversation:
Student: I bought your book on Amazon! Do you get any money for that?
Me: Well, yeah, I do get royalties.
Student: Do you get royalties if I bought a used copy for $1.87?
Me: Umm… no, I don’t think so. Maybe three cents.
Student (smiling): You’re welcome.
