Your mum gave me a book people give brides, by the way, back when the Strettons were making me do all the cooking. It's a book full of useful household charms, like for cleaning, plus recipes that are very difficult to make go wrong.

It's a great book. I still use it sometimes if I need to get a stain out and I'm not sure what charm would work best, and it had some really clever mending charms in it.

I don't think it would be quite the thing for Professor Siz, though. Also I think you're supposed to get it from your mum, not one of your students.
