> Imagine if in English, we only used Mr. and Ms. when talking to someone who's chronologically older, and had different forms depending on if the speaker is male or female, and furthermore it was considered very rude not to use the title where appropriate.

In parts of the South, you’re still expected to use “sir” and “ma’am”, particularly with strangers. Most speakers find this a bit old-fashioned or excessively polite, though.
