EL&U gets numerous questions along the lines of this one, asking how to deal with a communication "situation" between two parties.
Sometimes the communication is face-to-face, sometimes via email, sometimes via formal letter, but the basic fact remains that there is little in the discussions which have to do with the specifics of the English language itself, but rather the questions are about how to manage human-to-human interactions, be it (as in this case) how to broach a sensitive question without creating further animus, or (as in other cases) the appropriate greeting and salutation to use in an email.
Should there be a separate place for such questions, or, failing that, should they be closed as "off topic"?
