My father smoked when he was serving in the army but he was a Scot and gave up when he had to pay retail prices for cigarettes.
That was long before I was born and I grew up knowing my parents as non-smokers.
In spite of that they had an ashtray in the sitting room. In those days smokers wouldn’t have thought of asking permission to smoke and non-smokers wouldn’t have thought of refusing them had they asked.
That slowly changed but even though I hated the smell that clung to clothes and furniture it took me a while to realise that I had the right to send smokers outside.
Thankfully now I don’t know any smokers who’d light up in other people’s houses and they aren’t permitted to smoke in inside public places.
Today I’m grateful that I don’t have to put up with other people’s smoke.
