Having an author interact with you regularly on social media, promising sequels over a lengthy period of time while doing nothing but posting memes, capitalizing off his one books' success and not writing any sequels in a timely fashion.
I bought the first book based on reviews and friends and realized two years later I got Sibley'd and we'll never get a sequel.

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.

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!
