Smokers confuse me.

First off let me say that you should have the right to smoke whatever you want and YOU should be responsible for what comes from it, be it cancer, hallucinations or relief from pain. I should have the right to not breath what you are smoking.

Now for the confusing part.

Why do some smokers think it is okay to toss a lit cigarette from a vehicle or on the street?
Why do some smokers dump their ashtrays out on the street?
Why do some smokers leave their cigarette burning in the ashtray before entering a store? Are they planning on finishing it when they come out? Do they leave their car running as well?
Why do some smokers drive with their window down so they can blow the smoke out? Don't they like the smell? Does it taste good going in but smell bad coming out? Don't you want to get all the smoke you can out of each cigarette?

Why do pipes smell good while cigars smell like burning gym shoes?
Why do you need a cigarette before going to bed and one to get up? Do you smoke a "go to bed cigarette" backwards to wake up?
