Irritating Thing

It's impossible to keep contact information completely up-to-date at all times, and so naturally it occaisionally happens that an email message gets sent out to an invalid address. Now how is it that we learn of an email's expiration? Well, from another computer of course. We get one of those unfriendly messages titled something like 'failure notice' from a sender known only as the 'MAILER-DAEMON". Now surely no one actually thinks this 'MAILER-DAEMON' is an actual person, so why does the programmer responsible for such notices feel it's necessary to express the advent of a failed message in 'human terms'? This is what one such 'MAILER-DEAMON' told me today:

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to
the following addresses. This is a permanent error;
I've given up. Sorry it didn't work out.

Now here is a computer referring to itself in the first person,
offering apologies and condolences. How ridiculous is that.
