Great topic!
I too have a relatively small circle; neighbors, parents of my kids' moms, husband, and some online friends.
I am so enthusiastic about Vaping and having quit smoking that really I haven't given anyone I personally know a chance to offer anything negative to say. I hit them with positive after positive result and facts so they don't really even have a chance to be a nay-sayer. I had two online friends question the safety of Vaping but now THEY are also Vaping, if that gives you any idea of what I'm talking about.
The only places I really vape in the "wild" are vape shops or in my car. I don't vape in public because I didn't smoke in public or while walking down the street, so it's not in my habit. I will say that since I am not shy nor weirded out by being observed in public, I prefer to think that if someone were to see me Vaping in public that they'd be like, "that innocuous basic white woman is Vaping. Hm. Must not be the coming of the anti-Christ after all."
