I did a lot of explaining also. I felt like I was giving a seminar, but I didn't mind. My sister has emphysema and is still smoking. I brought along most of my equipment so I could allow others to try it.
I think I got at least 3 people to strongly consider
vaping (especially when they tried Dawn's Red Hots). I also spent some time trying to get some intrigued spouses and other relatives of the smokers to back off a bit. They were so impressed they immediately began to pressure my smoking audience. I took each off to the side and asked them to please let the smoker try this on their own and not set up hard lines and expectations. I know that if my husband had taken that tact, I would have dug in my heels and refused to give it an honest try.
I ended up handing out the forum address to many at the gathering. Oh, and my militant anti-smoking sister had no problem with me vaping in her house.
