I look at it like this. Whether or not we are aware of it, as vapers at this time in history, we are ambassadors of a very important advent. It's important because it is going to save lives.
With this in mind, let's be as courteous and well spoken about
vaping as we can. Good things will follow.
vaping in front of others needs to happen, or they will not discover it. But also,
vaping angrily or impudently is not efficient to the cause, because along with bringing the information to those who need it, we are also ambassadors of acclimating those who hold ill will toward cigarette smoke (and rightly so).
There is a right way to behave in public with your vapor, and a wrong way. Not trying to be controlling or judgmental - just thinking of the end result and the overall good.
