I agree that some people still don't know that ME vaping, even right next to them in a tiny space, won't affect them whatsoever.
Remember, WE use the clouds of 'smoke' to play tricks on our brains, to make them still think that we're getting a lung-full of the 'good stuff'... we have to keep in mind that those same clouds of vapor that trick our brains also tricks the brains of others who are unfamiliar with PV's (ecigs). While the trick may soothe us, it can also cause anxiety in those around us who just see a hazy cloud billowing around our heads and think 'Smoke'.
No need to be ashamed of it, but, just like smoking (or blowing bubbles with chewing gum, or anything else that affects those around us, whether it be audibly or visually or ummm... smell-ually? haha) just show a little common courtesy.
Frankly, if you were a non-courteous smoker, you'll likely be an non-courteous vaper. If you were an ashamed smoker, you'll probably be an ashamed vaper. The ideal combination would be if everyone were courteous, yet unapologetic for doing something that YOU want to do in a way that is reasonably accommodating to those around you.
Of course, that is only my
Happy Vaping!
