When I was a teenager in the 90s, I once dated someone whom I thought otherwise to be a smart and collected girl.
Then I watched her and her friend rummage the side streets for half smoked cigarette butts that people had disposed of out their car windows. The bliss in their eyes when they lit up a half smoked one.
Looking through the eyes of an adult now, it makes me wonder why I continued to try and strike a habit myself over the next 2 years. Fortunate for me, it never seemed like my drug of choice, though I did find others.
Being addicted to anything will make you realize just how fragile “giving a shit” really is.
