Fidelia is the feminine form of the Latin adjective that means faithful or loyal. It was popular among the Puritans but as people with the qualities of Fidelia have declined, so has the popularity of the name.

Fidelias are the most loyal women you will ever meet, to their parents, their boyfriends, their husbands, and their children. They never betray, never abandon, and never give up on the ones they love. Filled with compassion and empathy, Fidelias will do almost anything to help even a total stranger, anything except lie or deceive.

If a Fidelia tells you something, you know it's true, because Fidelias always tell the truth! Consider yourself fortunate if you have a Fidelia for a friend. Consider yourself the most fortunate man in the world if you are married to a Fidelia.

Fidelias are so trustworthy that they are often too trusting, to the point of being nieve. Their honest, kindhearted, and loyal natures make them especially vulnerable to being betrayed. Beware that if you betray a Fidelia, you will experience the wrath of the Almighty.

Fidelias are so beautiful and rare that most men assume they don't have a chance with one. Most men don't, but not because of their looks. What Fidelias really admire in men is their character. If you are a man of honor, don't be afraid to tell a Fidelia about your feelings for her, no matter how beautiful she is. She is attracted to men that are courageous, honorable, and value her as the rare treasure she is.
In all these years, my wife has never once cheated on me. She's a perfect Fidelia.

Most beautiful women are stuck up snobs, but that girl is soooooo sweet and beautiful. What a Fidelia!

Christian Fidelis 

A variation of meme who, upon making eye contact, will either absent-mindedly bite his top lip and wink at you or attack you with all manner of heinous verbal insults and accusations (with the occasional threat of anal rape). This is entirely dependent on the target's gender. A Christian Fidelis can often be seen wearing long sleeve t-shirts affiliated with any street wear label that charges over $100 AUD for cheap quality apparel. The majority of a Christian Fidelis' time is spent in the company of a Muche Shumba, a professional photographer and lord of "gathos". When not riding the Muche Shumba, a Christian Fidelis will either make attempts to get his attention or incessantly pester him for favours including, but not limited to:

- asking for photographs
- begging for compliments on fashion sense; hairstyle and "shoe game";

- and general approval and acceptance of existence.

The most effective way to successfully provoke a Christian Fidelis is to suggest that the relationship shared between him and the Muche has escalated from friendship to one where sexual activity is desired. The defensive mechanism a Christian Fidelis will employ in retaliation to said provocation involve:
- calling the offender a homosexual
- making a page on Instagram dedicated to roasting the offender
- crying to the Muche and other gatho veterans for support

One distinct physical feature found on a Christian Fidelis is a rapidly receding hairline.
Guy 1: "Hey, look at this photo taken by Muche Shumba."
Guy 2: "Hahaha look at his hair, it's the same as my grandpa's!"
Guy 1: "I know right, what a Christian Fidelis."

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.
