I know as a former alcoholic that I'm the least to point fingers but I do find it annoying to be around inconsiderate smokers. Actually I believe most smokers to be inconsiderate, at least the ones I've been around and I've been around many of them. Look at families woth smokers, especially when the smoker is the head of the home, most of them won't even go outside the home to smoke. They smoke in front of their children, spouse and guests. You know how it normally goes, we are the least kind to those we are suppose to love the most.
My brother and his wife smoke, but I've never seen them smoke inside their home or car because they have kids. Every time I've been around them they wait until they stop at a store or somewhere until they get out of the car to smoke.
