Quintrillion 

Not to be confused with quintillion. Quintrillion can be calculated as 1 trillion to the fifth power. As a numerical format it can be represented by 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. Or as some calculators will say “1e+60”. This number used in a percentage magnitude is still not quite as large as any kind of variation of pi but is the still larger than the socially common 100% or 110% as some people like to use. It can be argued that this number could be higher or lower than any kind of percentage used in the random spamming of the number keys on any phone, laptop, tablet, game controllers, typewriters, or telegrams.

Quatillion 

Quatillion is the largest number ever, and it is so large it is infinitely larger than infinity, and almost a quatillion times larger (but not quite, cos that'd be impossibly huge.) The sum to find one Quatillion is as follows:

1 Googol X 1 Quatillion

To put the imenseness of quatillion into perspective, if you had one quatillion grains of sand, you would not be able to fit even one jillionth of them into the universe. Nobody has ever done anything that warranted the use of a number so high as "Quatillion" as it is really big. In your life time, you wont do anything a Quatillion times.
No example warrants the use of "Quatillion" as it is just too big.

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.
