That gratitude post

That post I messed up about gratitude: I've just had someone do me an enormous favour: something that costs little, makes me very happy, and might upset a corporate mindset which doesn't see the little details which make up a big picture.
And the favour was done purely because someone, who doesn't know me at all, decided to do me said big favour. All I can say is that there is nice in the world, and if someday I can be less cryptic about how nice the favour was, I will. But for now, to keep the secret, let me just say

Yours, in obscure, but heartfelt gratitude,
N.
