English, perhaps due to the Danish and Norman conquests of England, has a larger vocabulary than most languages.
Acknowledged :)
But it still doesn't explain the tendency for that excessive use if phrases, euphemisms from English native speakers....
Other languages also have lexical funds large enough to use synonyms, idioms and slightly alter the meanings, but still don't use that possibility that frequently.
Idea behind that manner of speech is different. Here it is disrespectful to talk like that to the interlocutor, it is usually interpreted as a way to mislead or deceive.
English, the idea is not to offend the person, as far as I understood the intention of that practice, right?
