As I trotted along the crossway, I sort of wished that Sis hadn't decided to go after a husband on a luxury liner. On a cargo ship, now, I'd be climbing from deck to deck on a ladder instead of having gravity underfoot all the time just like I was home on the bottom of the Gulf of Mexico. But women always know what's right, and a boy can only make faces and do what they say, same as the men have to do. Still, it was pretty exciting to press my nose against the slots in the wall and see the sliding panels that could come charging out and block the crossway into an airtight fit in case a meteor or something smashed into the ship. And all along there were glass cases with spacesuits standing in them, like those knights they used to have back in the Middle Ages. "In the event of disaster affecting the oxygen content of companionway," they had the words etched into the glass, "break glass with hammer upon wall, remove spacesuit and proceed to don it in the following fashion." I read the "following fashion" until I knew it by heart. _Boy_, I said to myself, _I hope we have that kind of disaster. I'd sure like to get into one of those! Bet it would be more fun than those diving suits back in Undersea!_ And all the time I was alone. That was the best part. * * * * * Then I passed Deck Twelve and there was a big sign. "Notice! Passengers not permitted past this point!" A big sign in red. I peeked around the corner. I knew it--the next deck was the hull. I could see the portholes. Every twelve feet, they were, filled with the velvet of space and the dancing of more stars than I'd ever dreamed existed in the Universe. There wasn't anyone on the deck, as far as I could see. And this distance from the grav helix, the ship seemed mighty quiet and lonely. If I just took one quick look.... But I thought of what Sis would say and I turned around obediently. Then I saw the big red sign again. "Passengers not permitted--" Well! Didn't I know from my civics class that only women could be Earth Citizens these days? Sure, ever since the Male Desuffrage Act. And didn't I know that you had to be a citizen of a planet in order to get an interplanetary passport? Sis had explained it all to me in the careful, patient way she always talks politics and things like that to men. "Technically, Ferdinand, I'm the only passenger in our family. You can't be one, because, not being a citizen, you can't acquire an Earth Passport. However, you'll be going to Venus on the strength of this clause--'Miss Evelyn Sparling and all dependent male members of family, this number not to exceed the registered quota of sub-regulations pertaining'--and so on. I want you to understand these matters, so that you will grow into a man who takes an active interest in world affairs. No matter what you hear, women really like and appreciate such men."
