that would be a fine thing to say. Seems like everything is fine.

No it's not. My point is that "do the needful" is not a proper representation of Indian English, as the parent comment implied. There are a lot more pecularities that makes the dialect what it is, but people are just not aware of them (yet). A quick google search will tell you that.

"Howdy" seems like a successful synechdoche for American dialect to me. Seems like what makes something a proper representation is somewhat personal.

Not to derail the conversation more, but "howdy" is more of a southern American thing than just American. I never used that in the midwest/north until I moved to the south.

Yeah, I'm from the midwest and only would use it somewhat tongue in cheek or to mix things up. But most short-hands for American culture internationally seem to be focused on Southern/Western.

Yes it is. To the point where there is actually a meme about it: https://knowyourmeme.com/memes/do-the-needful

I'm South Asian by the way, so this meme is also associated with my own culture.
