I was only 13 years old, doing dumb things like that. When i was 13 there was a nearby store at which the owner would sell to kids. I thought he was so cool for doing that, but nope, not cool at all.
Then again I quit cold turkey when I was 21 and started back up again when I was 24 (I’m now 38), so apparently I was doing dumb ■■■■ in early adulthood as well.
Don’t feel too bad; my ex-gf started smoking just a few months ago, or maybe it was more like a year ago, and she just turned 40. I think she mostly smokes clove cigarettes, but still, pretty dumb for a 39 year old.
