Personally I wouldn't vape around kids. Studies have shown that kids who are exposed to cigarette smoking when they're young are more likely to become smokers themselves. I know part of this can be attributed to second hand smoke, but I think the Monkey See, Monkey Do factor is part of it as well. As a responsible adult I won't do something that I think might make a child susceptible to a vicious habit when they get older.
First of all, I completely agree with this.
Second, I can't be the only one who sees the humor in your comment vs. your avatar.
