Burble: make a continuous murmuring noise; speak in an unintelligible or silly way, typically at unnecessary length. (Oxford American Dictionaries)
This is the life of a young woman, with a good upbringing-however somewhat unusual and diverse past-causing friction, delayed growth in understanding some of life’s absurdities and expressing her frustration at the reader’s expense. This causes a build up of frustration and extreme emotional levels that beg to be dealt with and organized back into their rightful places.
This is to get these things off her chest, to vent. It is expressed in a way that the words expressed can be imprinted onto the internet for her future reflection or for her offspring and/or others to see.
Words in a book may fade. Words on the internet never die.
