Oh, my goodness! I’m dreadfully sorry! Something seems to have gone awry . . .  And here we were, having such a lovely chat.

Mustn’t let your tea get cold. I’ll put on another kettle while you push buttons, reload the page, and click thingy-ma-jigs. My sincere apologies. I’m sure between the two of us we can figure this out. Let me know if it keeps giving you the ugly 404 notice.
Something MUST be done! 

You know, don’t you, that I am quite fond of you? And I dislike anything disrupting our time together.
