This comic was inspired by what happened when one of my cousins spent a few weeks in the summer with us. It was the 80s and nearly every adult I knew, including my mother, smoked. She smoked in the house and in the car.
We (mom, cousin, sister, and me) were driving someone and my cousin started coughing. She told my mother that she was allergic to the smoke and asked if she could put out the cigarette. My mother told my cousin "...you know I smoked when you wanted to come over. Open a window!"
