I was Earth’s delegate to the United Planets—or more precisely, a candidate, though that isn’t right either, since it was not my candidacy, but all humanity’s which the General Assembly was going to consider. Never in my life did I feel so nervous. My tongue was thick, my mouth dry, and when I walked out onto the red carpet spread from the astrobus, I couldn’t tell whether it or my knees were gently buckling under me. Speeches would surely have to be given, but I was too choked with emotion to stammer out a single word, so that when I caught sight of a large, shiny machine with a chrome counter and little slots for coins, I hurriedly inserted one, placing the cup of my thermos underneath its spigot. This was the first interplanetary incident in the history of human diplomacy on the galactic level, since what I had taken for a soft drink vending machine turned out to be the deputy chairman of the Rhohch delegation in full regalia. By a great stroke of luck the Rhohches happened to be the ones who had offered to sponsor our candidacy at the meeting, though I didn’t know this at the time, and when that high dignitary spat upon my boots I took it as a bad sign, while in fact it was only the aromatic secretion of his salutation glands.
