A wizard is never late.

That's from Peter Jackson's movie. Tolkien's Gandalf knew when he was late, and apologized.

And that, Frodo, is the end of my account. May Elrond and the others forgive the length of it. But such a thing has not happened before, that Gandalf broke tryst and did not come when he promised. An account to the Ring-bearer of so strange an event was required, I think.

Dominus's account is near the end of his Higher Order Perl page.

I ran outta gas. I had a flat tire. I didn't have enough money for cab fare. My tux didn't come back from the cleaners. An old friend came in from outta town. Someone stole my car. There was an earthquake, a terrible flood, locusts. It wasn't my fault!! I swear to God!!
