one

one thing i simultaneously like and dislike about english is the use of the term "one" as a sign of generality or impersonality. "one shouldn't do that" or " in these cases one usually goes to the hospital". i like it because i keep imagining who this "one" person is. is he tall, fat, sttuborn, is he always the same "one"? but i also dislike it because, poor little one. always having to show up whenever one doesn't know who to refer to, as in this very sentence i've just written.
