Thanks for the welcomes, all. I'm really not bothered by my friend, like I said. She's not into sci-fi anyway as a rule, and we are pretty darn sarcastic all the time. The next day, I mentioned that I'd found ebooks of the entire series and she's like, 'why do you text me updates on things like this' and 'I don't think we can be friends anymore' and all that, and I joked back. It's all good. No real embarrassment. I don't know, maybe it's the university environment, but no one really cares.
