Hi Paddy’s I was reading about the newspaper today and that’s why I am not asking you if you want to come over tomorrow

Why isn't y'all acceptable? Voi is the plural, right?

I did the correct one yet it still marks it as incorrect

So is tu singular you and voi is plural you? Like the french tu/vous?

That was very weird because I done the same thing

I have gracefully answered using the right words and the system told me I did it wrong :-(

I was correct on this, so I don't understand why it said I was incorrect.
