乌尔夫说，当你代数时，我喜欢你 - 立即后悔。这是一个轻巧的戏剧性 - 描述某人，因为代数无疑是要越界的。您通常不会将普通朋友描述为代数，然后说您喜欢她。
(I like you when you're algebraic, said Ulf--and immediately regretted it. It was a flirtatious remark--describing somebody as algebraic was undoubtedly to cross a line. You would not normally describe an ordinary friend as algebraic, and then say that you liked her that way.)
