Sometimes I am absolutely astounded by the ignorance of people.
I told one my friends about the time I saw fresh water dolphins in the Mekong river in Cambodia, and she responds that I didn't. Dolphins don't live in rivers she says. When I told her I saw them with my own eyes and took videos of them, she said that they must've caught them from the ocean and put them in the river for tourists. This statement was so dumb I didn't know how to respond. That she said this with so much confidence and certainty in her voice is what bewildered me. I just told her to look up freshwater dolphin species.
I met a girl who worked at Yosemite National Park and she said she would sometimes get tourists asking her to "turn on the waterfall."
I also met people who complain about beaches being too small not realizing they were there at high tide.
What's the dumbest thing you heard people say?
