Are either of them online? They could find out from your blog or if they Googled you.
Nobody knows I'm using my middle + last name for the book, and my relatives are thankfully not tech savvy enough to go digging. (I would have turned me up in about 2 seconds...)
And it's not that I'm trying to keep it a surprise, I'm attempting to control the flow of information.
My mom likes to think she understands everything (can never admit she's wrong, yay), and so she'll go tell everyone all sorts of wild and crazy things she's extrapolated. (And then it's my fault for not explaining.) Having tried various things over the past year and having most of it backfire, turns out the best policy is just silence.
I'm waiting until I have my new website up and all the text for all the listings is correct (we had a little issue with the blurbs on Amazon) and THEN I'm just going to make a blanket announcement on FB so everyone will get all the CORRECT info at the same time, hooray. Anyway all of this should happen in the next week or so and then all of this nonsense will be OVER.
