You're saying that trying just one cigarette makes you addicted to it? I mean, everyone probably tried smoking in secret with his friends when you were still in school, right? I did that too and just a while ago, I felt like trying it again just for the hell of it. I know I shouldn't smoke since I have Bronchitis and stuff but I still did it because I just wanted to properly try it again. I smoked a full cig and I won't smoke again since I just don't like it.
But I have nothing against people that smoke, I don't even know why people say you shouldn't smoke. It's up to the persons, why tell them they shouldn't smoke when they want to?
Oh and by the way, do you think that swearing somehow makes you look grown-up?
