Unless Anon is willing to put in some serious work, like properly going back to school or busting their ass learning (and getting good at) a trade, then their life is kinda fucked.
You can't just crawl out of almost 20 years of NEETing into really any kind of job, especially without the charisma to at least try masking it.
Also fuck knows why Anon's parents just let them drop out of school and basically cease to exist outside of playing videogames for best part of two decades. That's plain bad parenting.
It ia very much an English speaking world thing, but I wouldn't say US-centric as we have basically the same greeting in the UK.
Yeah, that wouldn't fly as much here either - if somebody asked how my day was, I'd be inclined to think they want a summary at least.
