We turned out to be a row or two away, made no difference at all.
But, they both smoked heavily, continuously in the car and at home too. My whole family did. Grandparent, parents, siblings (2 of 6 didn’t), step parents, aunts and uncles. Growing up it felt much odder and rebellious to not smoke.
In addition to the ash trays my father insisted he use little heavy, silver tubular extinguishers in each ash tray. Silver plated, from memory. Doubt they did much, but were ubiquitous at home.
My father was proud when he “gave up smoking” by moving from Gitances to Silk Cut, which he said were like fresh air compared.
