In English, we use "one" to avoid repetition. (We also use he, she, it, and whatnot, but I know how to use those!) For example: "The post office ate your letter. Will you write me a new one?"
How is the idea of the "one" rendered in Russian? Is there a similar pronoun, or is this dealt with a different way?
