What is a one-sentence summary of the following article?
Hold the cigarette between your index and middle finger, somewhere on the filter. Exactly where to hold it depends on what's comfortable for you. Be wary of the lit end of your cigarette when holding it idly. It is considered bad etiquette to burn someone or something with your cigarette. If you have to point or gesture toward something while talking, you use your other hand. The hand holding the cigarette should be relatively still except when bringing the cigarette to and from your lips. If you're in someone's backyard, or in their car, don't light a cigarette without asking. If someone doesn't want you smoking on their property, be respectful of this. Don't throw cigarettes into trash cans without fully extinguishing them, as cigarettes are a fire hazard. Don't thoughtlessly throw finished cigarettes onto the ground. That is littering. Your finished cigarette should be extinguished into an ashtray or hard surface, and then thrown away.

Summary:
Hold the cigarette properly. Don't gesture with the cigarette. Ask before you light up when on someone else's property. Manage your butts responsibility.
