More from Nick Hornby's High Fidelity, on what really matters at the onset of a potentially serious relationship:
A while back, when Dick and Barry and I agreed that what really matters is what you like, not what you are like, Barry proposed the idea of a questionnaire for prospective partners, a two- or three-page multiple-choice document that covered all the music/film/TV/book bases. It was intended a) to dispense with awkward conversations, and b) to prevent a chap from leaping into bed with someone who might, at a later date, turn out to have every Julio Iglesias record ever made.
It amused us at the time, although Barry, being Barry, went one stage further: he compiled the questionnaire and presented it to some poor woman he was interested in, and she hit him with it. But there was an important and essential truth contained in the idea, and the truth was that these things matter, and it's no good pretending that any relationship has a future if your record collections disagree violently, or if your favorite films wouldn't even speak to each other if they met at a party.
