What's an Author To Do?

Okay, for a minute there my books were selling like hotcakes! At work I was selling like 2-3 books a day as the word spread about my recently published novel. It was really cool! Things have slowed down quite a bit, but that was to be expected. What I didn't expect to learn is that, rather than some people buying their own copy, they've been reading a book purchased by someone else. WTF??? One coworker was walking past me the other day, and she was like, "Girl, I didn't know you wrote a book." Then I'm thinking, cool, she wants to buy one. WRONG! Then she says, "Yeah, so and so gave me a copy and I was like, L.A. Jefferson...that woman on the back cover looks just like LaCharmine. Then OHHHH that is LaCharmine. I'm liking it so far..." While I was glad she was enjoying it, I would have much rather preferred she bought her own. But, it happens, I know. I, myself, have borrowed someone else's copy of a book. Not because I was too cheap to buy my own, but because they offered it to me. Soooo I won't cry over spilled milk. What I will do is push my book sales even harder to compensate for the those darn book sharers!
