Most of the people I've come across are cool with it, so I'll let them hold my PV, look at it, and ask any questions they might have. Sometimes, if I know they're interested, I'll let them take a hit. I always try to answer their questions as best I can, of course. The most common one I'll get is, "Does it contain nicotine?" to which I'll reply, "Yes, but you can get them without the nic, also." Every now and then I'll be vaping and someone will look at me funny. When that happens, I just explain to them that it is a reduced-harm alternative, meaning that I get the effects of smoking without all of the nasty chemicals and whatnot. Most seem to be okay with it after that. Some will even tell me, "Oh, that's awesome. I should get my spouse/family member/friend to try that." Of course, I work for a vape shop and know of the majority of the ones here, so sometimes I'll point them to a place where they can get one if they want to try it out. I've never really had anyone say, "Please don't do that around me." For which I'm thankful!
