My daughter used to answer her friends questions about it, said I was ridiculous and then she'd open the cupboard where I had a huge juice and supply stash and refer to it as my .... lab. They are kids. Kids do that. They also refer to it as my crack pipe. Whatever, but they appreciate the fact that I am not polluting their world with cigs. They'll bring their smoking friends to me in hopes of them getting off the cigs.
Most of them don't want to go head to head with the teasing game, I'll take their teasing and I'll give it right back at them.
I did have one gal I was working with ask while I was standing outside with the smokers, hitting on my chuck "Don't people laugh at you?" I just said well, people always have laughed at me, what's this have to do with it. Honestly, I don't give a rats behind. After 28 years of smoking I quit. And yeah, I smoke a big mod that seems to bit a bit more obnoxious than the average e-cig.
When I watch people smoke, ones my age, knowing they've hit the point where it seems really hopeless and the young ones who think that when they get alittle older they can walk away from it (yeah, right) I don't feel self conscious about it at all and I feel sad for them.
I look in the mirror, as a 44 year old woman, then I feel stupid and silly, at all the premature wrinkles I gave myself over the years. Now, tease me about that or my .... and I will truly be upset.

Tease me all day long about my pv, I just don't care.
