Hello, cancer cadet, this is your conscience speaking...If you have such little regard for your life that you insist on being a voluntary self-pollutant go right ahead... but little kids really are impressionable: the magazines aren't lying.
You are doing your younger sister a disservice by giving her cigarettes and teaching her to smoke. Like alcohol, driving a car, and pornography smoking is an adult vice.. with risks associated for use, no less.
Of course smoking is pleasurable, that's why people do it. That's why even I do, every now and again. But your sister cannot possibly comprehend the risk she's taking, she likely hasn't even been thorugh DARE programs and seen a picture of a blackened lung, and she probably thinks cancer is something only old people get. Her own mortality? Rest assured that few children that young even give such things a thought.
You, friend, have done your sister a grave disservice; and you, friend, are a terrible sibling. Lock yourself in a closet and suck up the tumors, maybe when you get a tracheotomy your sister will see it fit to quit.
None.
