My uncle used to do that. Used to sniff the pots and pans when we were kids and use his own to cook. Super zealot. He’s 92 and still unimaginably crazy the same way. But he’s also been declared mentally insane since too much LSD back in 1967...
Your uncle had a lot of fun!!!
I know a vegan who just moved here. Very nice woman, smart too, but she’s a vegan. I invited her over for dinner. I was roasting a chicken for Thanksgiving and said, well, just come for the veggies. She said the smell of cooking meat would make her sick. Another vegan here doesn’t seem to have that prejudice.
