Rejection

Famously, the British Museum used to have a form letter, which they would use to reply to many of the enquiries and questions they would receive each year about the collections, ancient history, culture so forth.  It read something like:

I regret to inform you that your letter has not been selected for reply.

Note the subtle paradox of a response telling the member of the public that this is just what he or she is not going to get.

I've now come across a more up-to-date equivalent for our modern world.  It reads:

I could find no compelling purpose in answering your email.
