Question of the Day!

I know that there are a lot of parents out there that will do anything to protect their children from any harm or danger that may come to them. So here is my questions. Why do parents that smoke insist on smoking around their children? Is the addiction that strong that they would risk their children's life just to feed their habits. Don't parents know that what they are doing to themselves they are doing to their children in an even worse way. I thought about this while sitting at the bus stop one morning and saw a man smoking a cigarette at 6:30 in the morning. He probably did have his morning coffee yet and he is smoking. Then I thought about that mothers and fathers that drive their children to school at 7:00 in the morning and how they are sitting in the minivan smoking with their 5 or 6 year old and sometimes a new born or a 8 month old. And to justify their actions or to say that they are protecting their children they have the window open while they smoke and drive. I'm not a smoker so I don't get it. What's more important actually mentally and physically protecting your children or feeding your habit?
