Oort Cloud Fallacy
"The Oort Cloud Fallacy occurs when someone argues that something must exist or be true simply because it is theoretically possible or hasn't been definitively disproven—especially when the claim is distant, vague, or unverifiable. The fallacy draws its name from the Oort Cloud: a hypothetical region of icy bodies surrounding the solar system that has never been directly observed but is widely accepted due to indirect evidence."
"Hey John, do you believe God exists." "We have no proof he doesn't so he must." "Oort Cloud Fallacy."

Back when I lived in upstate new york
A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

TLDU
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
Me: Woah! TLDU!
