Very sad news. I grew up with Sir Terry. Somewhere I have a letter he sent to me in reply to a (rather gushing) fan letter a teen-aged me wrote to him about, IIRC,
Soul Music. He'd clearly read my letter, and answered it personally. I thought that was great, still do.
His writing has passed into our everyday use. Bad hair has been a Magrat day since
Witches Abroad. We often cook 'curry with named meat' in
Chez Morrisette, cursing the goddess Anoia when the ladle gets stuck in the drawer....
How can he be gone? This has made me very sad
