When I was in high school, I once had a conversation with a classmate that went something like this (except that it was longer and I was less eloquent):
Him: "German is a Scandinavian language."
Me: "No, it's not. German and the Scandinavian languages both fall under the umbrella of Germanic languages, but 'Scandinavian languages' refers to a narrower category that doesn't include German."
Him: "Well that's your opinion."
Me: "No??? That's not what an opinion is???"
Him: "Look, it's your opinion that German isn't a Scandinavian language, and it's my opinion that it is. We can agree to disagree."
Me: ??????????????????!!!!!!!!!????!?!?!?!?! *punches self in face*
When I was taking a required intro biology course in college, I had already read a bunch of LW and SSC, notably including That Chocolate Study. So when the professor put Bohannon's results and methodology up on the projector, I was ready as heck to talk about all of the atrocities therein. The professor asked us to pair up with the person next to us to discuss whether we believed Bohannon's results, and I decided to give the freshman next to me the chance to speak first before I absolutely demolished everything. The girl turned to me with wide eyes and a confident, creaky-voice drawl, and said, verbatim: "I think it's true, because chocolate is known to be a superfood."
I was floored. How could this be happening in real life? I was at an elite college with a sub-10% acceptance rate, and this person next to me had just said "known to be" and "superfood" like they explained anything – like they meant anything. I will never forget those words. Looking back, that may have been the day I decided to move to the Bay after graduating. No regrets.
