Yeah I've experienced this also. When people inquire about my e cig I pretty much get out my soap box and give an entire presentation. Some people think I've lost my mind, a nice amount of people are highly interested and attracted to the it, and a few I think want to have me hung.
Heh, this reminds me of an incident I had about ten years ago with a rabid non-smoker. I was still smoking at the time, and was outside of the building at work taking a cig break, and the wind shifted and was carrying the smoke over to the entrance.
She comes walking up to me with a nasty look on her face and just rips into me about second hand smoke and how irresponsible I am, and blah blah blah... (I say absolutely nothing the whole time, just stand there smoking with an amused expression) She ends her little tirade with "People like you should be hung!"
I cocked an eyebrow and with the slyest smile I could muster, I said, "I am. How kind of you to notice."
I've never seen anyone's face get so red so fast.
And now back to our regularly scheduled topic!
