Good for you, Grizabella!
I am outgoing, but when it comes to things I consider personal, it's not about fear or shame, but just that I choose to share certain aspects of my life with certain people. Not a lot of people know I read just because it doesn't come up and it's not like I wear a sign (well I would if I read for others!).
Your story brought something to mind something that just happened a couple days ago. I was talking to someone about a book we were both reading and I was surprised it had the word alchemy in describing it when that's not really what it's about. And she said (she being fairly conservative) with a grin, are you telling me you were a witch in another life? And I said or in this one....don't know why I said that, was just a spur of the moment thing to say, do not consider myself a witch (maybe a Wise Woman in Training), but I did get an interesting look and the topic was just dropped. OK maybe some times i just find it fun to stir the pot (or cauldron) lol.
