Sorry. I feel no obligation to protect grown adults from answering the questions of their children, or children from asking questions. I feel less obligation to protect parents from having to teach their children the difference between vapor, steam and smoke.
Good Lord! Would you restrict all your public activities only to things children can understand without having to ask their parents questions? Children SHOULD have to ask mommy stuff. They should be encouraged and even forced to ask questions. They should always be in situations where they need to ask questions. How intellectually stunting if it were otherwise?
If you are unaware of something, I'll be glad to enlighten you. But don't expect me modify my behavior for no other reason than to cater to your unawareness. If I did that, I'd only be perpetuating your ignorance and nothing would ever happen to make vaping more socially unremarkable.
