I asked him “what color were the clouds back then?” and he said they were white. I asked him what happens if I take an orange light and light up something that’s white with it. He ignored me. He went on about how everyone in his age group remembers the Sun being orange, and by me questioning him, I’m calling him and all his peers liars and I’m stupid because I’m younger than him and vaccinated.


This is an old Mandela effect.
The issue is that they don’t actually remember what the sun looked like, because you can’t really look at the sun.
Their memories are of the crayon drawings that they made in school.
