The Libran Librarian

I once had this conversation with a leggy beauty at a bar.

"So what do you do?" I asked.

"I'm a Libran," she replied, or so I thought.

"Oh, OK, I'm a Cancerian, but so far, it hasn't been quite a full-time occupation for me," I chuckled like I was really, really smart.

"Eh?"

"Erm, yeah. So what does that kind of a job involve?"

She looked incredulous and off-kilter for reasons I could not fathom at that moment. "Uh, books?"

"Oh ... books on astrology?"

"On almost everything. Excuse me, but are you OK?"

"Well, this is my seventh whisky, but I'm not seeing purple elephants yet, thanks for asking. Anyway, how did you land such a position? Do they advertise it in the papers? Like 'People born in October needed. Other signs need not apply'. Hehehehehehe!"

"Excuse me, but I think there's some confusion here."

"Eh? Didn't you say you work as a Libran?"

Boy, the eighth shot of whisky sure tasted damn good.
