¿Porqué el inglés no tiene equivalente a lo formal "Usted"?
In English we don't have a formal version of YOU but we do have other ways to make the sentence formal in the language.
Just by adding PLEASE in a request makes it more formal...
Instead of using "Can you do me a favor? "
"Could you do me a favor?"
also makes it more formal, and a lot of other ways that we can study more about in a lesson or other videos :)
