A Complaint about Correspondents, Dated in San Francisco is a short story by Mark Twain, one of the most funny and beloved American authors of all time. In it, Mark Twain complains about the letters he gets from friends and relatives. Letters which hold not a word of anyone he cares about or anything that would interest him, but instead are filled with nothing but utterly boring drivel, telling him about people he's never heard of before, and things he knows nothing at all about and cares less.
