X先生的回复英文版放在这里了。
“If anonymity bothers you, I'm afraid I've kept worse company. But since you've already taken the Cartesian liberty, by all means—name me in your own way. Just don't call me ‘X’ to my face. I'm rather attached to being an unknown. Unknowns, after all, get under the skin far more efficiently than the well-defined.”
末尾又添了一行：
“As for what I should call you in return—since you sign yourself Marguerite and hide behind daisies, I suppose I'll simply call you Miss M. In mathematics, M is the letter reserved for implicit equations: beautiful, elusive, and generally unsolvable without the right boundary conditions.”
