Smoking

I like picking up my son from the school everyday but sometimes I notice that some parents are smoking in their car with their kids in it. Why they can not wait until their kids are not around before they smoke, I wonder if they are smoking alec bradley cigars. Their kids are in the school seven to eight hours a day and thus hours when they are away from home I am sure the parents are smoking a lot so why wait until they pick up their kids to smoke. I wish they would never smoke around their children I know it is not my business but I feel bad for the kids.
