Yeah, I moved from the US to Europe in 2021 and wore a mask daily everywhere outside of my bedroom (I had eight housemates, including a very nutso Q person, who was trying to get covid to hasten his natural immunity and who did not shower for the ten months we lived together- he was the second worst roommate) until probably June of 2022. It wasn’t until then that I realized I have allergies to things that grow on this continent that I never encountered at home.
