My 19-year-old brother got caught smoking cigarettes after a work day at his father's house (we have different fathers). His father busted him and told my mom. My mom went into hysterics. When I say hysterics, I mean she called me at work crying on the phone and threatening to kick him out of the house altogether. Smoking cigarettes to her is the equivalent of peddling crack on a street corner; in fact, she may have been less upset if this had been the case.
My brother, for all his scruples, told me that he had succumb to peer pressure and began smoking a few times ("casually" as he says!) with his friends over the course of the last two months. He's not addicted, he says. It's just a casual, peer thing. However, this does not explain why he had to smoke after work while he's at his father's house (far removed from his schoolyard friends). Plus, I've never known a smoker that just up and decided to start filling their lungs with tar and tobacco - it always seems to start as a casual thing. First with some friends to fit in, then after a long day and then the days become longer when you don't have a cigarette.
As a non-smoker (okay, I dabble in cigars every now and then), am I being naive or what?
