“One of the major problems encountered in time travel is not that of becoming your own father or mother. There is no problem in becoming your own father or mother that a broad-minded and well-adjusted family can't cope with. There is no problem with changing the course of history—the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be descibed differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is futher complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father.Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later aditions of the book all pages beyond this point have been left blank to save on printing costs.The Hitchhiker's Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term "Future Perfect" has been abandoned since it was discovered not to be.”

“One of the main problems encountered in time travel is not that of accidentally becoming your own father or mother. There is no problem involved in becoming your own father or mother that a broadminded and well-adjusted family can’t cope with.”

“We have normality. I repeat, we have normality. Anything you still can't cope with is therefore your own problem.”

“..."Fun?" you ask. "Weren't feminists these grim-faced, humorless, antifamily, karate-chopping ninjas who were bitter because they couldn't get a man?" Well, in fact the problem was that all too many of them HAD gotten a man, married him, had his kids, and then discovered that, as mothers, they were never supposed to have their own money, their own identity, their own aspirations, time to pee, or a brain. And yes, some women indeed became bad-tempered as a result. After all, no anger, no social change.”

“Your past is not as important as your future. Did you know that? Can't change anything about what you've been, but you can change who you'll become.”

“And then, one Thursday, nearly two thousand years after one man had been nailed to a tree for saying how great it would be to be nice to people for a change, a girl sitting on her own in a small café in Rickmansworth suddenly realized what it was that had been going wrong all this time, and she finally knew how the world could be made a good and happy place. This time it was right, it would work, and no one would have to get nailed to anything.”

“The Restaurant at the End of the Universe is one of the most extraordinary ventures in the entire history of catering.It is built on the fragmented remains of an eventually ruined planet which is (wioll haven be) enclosed in a vast time bubble and projected forward in time to the precise moment of the End of the Universe.This is, many would say, impossible.In it, guests take (willan on-take) their places at table and eat (willan on eat) sumptuous meals while watching (willing watchen) the whole of creation explode around them.This, many would say, is equally impossible.You can arrive (mayan arrivan on-when) for any sitting you like without prior (late fore-when) reservation because you can book retrospectively, as it were, when you return to your own time (you can have on-book haventa forewhen presooning returningwenta retrohome).This is, many would now insist, absolutely impossible.At the Restaurant you can meet and dine with (mayan meetan con with dinan on when) a fascinating cross-section of the entire population of space and time.This, it can be explained patiently, is also impossible.You can visit it as many times as you like (mayan on-visit re onvisiting ... and so on – for further tense correction consult Dr. Streetmentioner's book) and be sure of never meeting yourself, because of the embarrassment this usually causes.”
