Reminds me of when I was still vegan. People tend to have some weird head canon at play, no matter the topic.
I mentioned I cooked some delicious food but because they knew I was vegan they started babbling on about how they had meat today even though they usually don't eat that much meat. I don't now if it's just some automatic response when they don't have anything of interest to speak of.
The issue is with them, not you/us.
