One more NC-17-ism...this is it...I promise.
I have been smoking - on and off - for too long. Far too long. I was a social smoker for a while, which meant I only smoked when I drank.
Or in dire emergencies.
Or on Tuesdays.
Back in the days when you could still smoke in bars, I was once berated for smoking by a stranger:
STRANGER: Smoking's a dirty habit.
ME: (exhaling all over the guy) It's not a habit. It's a hobby.
