A friend of mine, pursuing BA(Hons) in English corrected me that no one uses shall now and often it is advised to prefer the use of should, would, etc.
Although Downton Abbey is set upon a time period decades ago, the characters make use of "shall" frequently in their sentences, I have noticed in some British movies and shows that the character make use of "shall" quite often. I couldn't help but notice that I never came across and American character making use of "shall" in an American TV show or movie, or maybe I missed catching the character making use of it.
What is with "shall" in this present-day? Is it obsolete now? Was it only used until contemporary era?
