yeah I was thinking about teaching and tutoring English for intermediate to advanced students who want to understand nuances of things like slang, poetry, technical / legal / medical jargon, and so on ... because I think there's lots of finer points about English which aren't even taught anymore, and even native speakers are often rubbish communicators and thinkers because (in part) they have an incurious and intellectually lazy approach to their own language ... sadly, this only makes it easier for them to be brainwashed by government and media who tell the truth in only 4 situations:
1 - where it is trivial
2 - where it's in their own interests
3 - where they're forced to
4 - where it is to sell you a greater lie
... and I also note how many people are blissfully unaware that legalese was intentionally designed -- and this is taught when you study law, so it's not even denied -- to prevent people understanding the process, so they wouldn't know if they received justice or not
Imagine what it is like for foreigners to understand all this when even the locals have forgotten or never knew
