When I started smoking, I was so afraid that the smell would stick to my fingers, so I devised a new way of holding my cigarettes. I'd hold it like a joint, but inversely, so the burning end would be facing me, then I'd turn my hand around so that my three remaining free fingers would be cupping the side of my chin whenever I took a drag. Sure it looked ridiculous, and sure a number of people commented on it. The exes I went through during that period were not particularly fond of it, but did I care? Anyhow, I realized that my mom wouldn't sniff my fingers, so I stopped doing this eventually.
I used to hold the lighter well away from my face when I lit it up, then slowly brought the flame to my cigarette. Pretty sure my close friends would remember that habit, because they still bring it up once in a blue moon when we're all talking about my peculiarities. I guess I've always had a fear of getting my eyelashes singed off by an unruly flame. I also stopped doing this after a while. It's not very effective when there's a strong wind blowing, and it's a waste of lighter fluid.
I chain-smoke when I'm in a social situation, which is why I tend to be a hermit.
And contrary to popular belief, I will quit smoking one day. Someday.
