Derived from Robert Louis Stevenson's popular novella, "The Strange Case of Dr. Jekyll and Mr. Hyde"

Dr. Jekyll is a respected doctor and friend of both Lanyon, a fellow physician, and Utterson, a lawyer. Jekyll is a seemingly prosperous man, well established in the community, and known for his decency and charitable works. Since his youth, however, he has secretly engaged in unspecified dissolute and corrupt behavior. Jekyll finds this dark side a burden and undertakes experiments intended to separate his good and evil selves from one another. Through these experiments, he brings Mr. Hyde into being, finding a way to transform himself in such a way that he fully becomes his darker half.
"If I ever needed further justification for my experiments, gentleman; you have just provided it."
Jekyll by Romolo September 3, 2005

Jekyll and Hyde Parenting 

A style of parenting that provides a full spectrum of emotional and psychological experiences to a child vis-a-vis the parents’ instability and addictions which lays the groundwork for years of in-depth psychotherapies in which the child, throughout their lifespan, has the opportunity to undo the warp and find some semblance of balance and potentially, a sense of a true self.
Yup, at our house it was nose-to-the-grindstone discipline during the week and then Mr. Toad’s Wild Ride when the weekends rolled around; my parents were practicing devotees of Jekyll and Hyde Parenting.
Jency is a one of a kind name. Not many people
have it, in fact it's a name gifted only to people
who are naturally kind, sweet and attractive. If you
ever meet a Jency, never let them go and always
take care of them because they'll always have your
back. They can be so caring and if you get lucky enough you can experience their vulnerability
which is the most beautiful emotion you can ever
feel. They're love is so strong and pure it's almost
impossible to like them.

A Jency is an extremely sexy and playful girl, usually from Singapore. She is a total nerd and loves to play online games, but she also has a wild social side, often staying out all night clubbing and drinking with her friends. She may seem innocent at first glance, but there is a naughty side once you get to know her.

She is very smart but also very lazy. She procrastinates doing her homework until the last minute, but luckily she is smart enough to still pass her classes. She also has a very funny sense of humor.

She is short but sweet. Her body is perfect, with the most amazing dark brown eyes you've ever seen, and a sexy butt and a nice, perky chest (not too big -- just the right size). Her accent is funny and her laugh is contagious, just like her gorgeous smile.
"Wow, that girl is sexy and smart at the same time?! She must be a Jency."
