The motorcycle he can't legally nor physically ride. The "classic" car he can't legally drive. The absurd quantity of Apple products and unused VR headsets. It explains everything. The invented jobs and credentials he would imagine a successful young woman would have. It's his coping mechanism for what a miserable failure he is. He is bitter for any occasion he is forced to take responsibility for his poor choices.
To me it sounds like delusions of grandeur and self-importance. I know someone that has to deal with someone that's growing into being exactly like Wu. She's 20 years old, unemployed and living off her parents and can't imagine taking a regular job to earn money, experience and independence. It has to be high-profile job with status where she gets to be in charge, have hiring/firing power and makes big bux without doing much actual work or have any prior experience.
Despite having parents with money that funds her lifestyle and a sheltered upbringing she's resentful towards them and imagines she's had a tough life, tougher and harder than everyone else's.
Her CV is four pages long despite never actually doing anything of value and it's filled with exaggerations, trumped up achievements, falsehoods and what can charitably be called lies. I mean, who lists courses one flunked multiple times or dropped out of during the first weeks as a merit? Without mentioning the flunked/dropped out of part, of course. She's a Flynt in training, except being a cis-woman.
re: Wu's car and the engine harness.
When she bought that fag-box there was a lot of bragging about being an engineer and how as an engineer he would easily remove and install a new engine harness and have you ever heard of a woman doing that?
Fast-forward a few weeks and Wu twitters about going to the auto-shop and is informed that installing a new harness would cost $1500 or so, might not even include the price for the part I'm not sure.
Now he's asking twitter about where to get one and getting angry when a cis-man explains where to look.
There might be more in the saga of the Audi that I'm forgetting.
