A perfunctory conversation with Mr. Dursley about the matter of confirming a meeting time.

Durs: We're aiming for 6.30 tonight aren't we?

Me: We are. I shall appear to you as closely to that time as humanly (not spectrally) possible.

Durs: Lovely! I shall adjust the flat's atmosphere to Earth normal in time for your arrival.

Me: Sploonberbenak. (Gliese581Dian for 'Thanks')

Durs: Your customs are strange to me, Lizard man, but your race's rule over us has been an undeniable success.

Me: It is customary for us to thank the inferior humans when they accommodate our needs without forcing us to resort to violence. You have abided by this rule, and, therefore, you deserve my gratitude (in this instance).

Durs: Thanks! I voted for your people in the top secret Amphibia vs. Insecta ballot of 2009 to elect our favoured Earth Overlords. I voted for you, because your Emperor seemed like an approachable people person, while the Insect Emperor called me a bigoted woman for saying that I disliked his mandibles.

Me: By mentioning the Insecta you have offended me. Upon my arrival at your residence this evening you will be vaporised.

Durs: Well vaporisation is any invading Reptilian's prerogative and, while I personally disagree with this course of action, it is not my place to question the greater intellect of my Reptilian rulers. Since you seem determined to carry out this vaporisation, I just thought that I would apologise in advance for being unable to vote for your people in the 2012 elections. I will place a large rock to the right of my front door, for you to cool off on, following my vaporisation.

Me: I will bring a ballot paper upon which you can mark your vote prior to your vaporisation. I will then submit the vote upon your behalf next year. Please make sure the rock is placed in a refrigeration unit for at least 1 hour before my arrival.
