But Can She Do Maths?
I am grinning ear to ear after reading this. So funny and clever and beautifully characterised. I loved it all, from the Friday-night whirlpool-and-lonely-hearts ritual to the maths geekery and the complete upending of every dating cliche in the book. There's so much to love here, I can't even quote back the good lines or I'd have to copy and paste the entire story.
And I finally have a perfect reason to use this icon! Thank you for this delightful fic.
