When I mentioned to Stella that I was considering learning shorthand, she said she had wanted to learn shorthand for quite a while, too, and that she would be up for learning it together with me.
So, perhaps we’ll have to see.
(My current favourite is Stiefografie; Deutsche Einheitskurzschrift may be more wide-spread and “standard”, but the use of pressure/stroke width turns me off a bit. And using something geared to German means both of us can use it. And I have no idea where I’d find information on, say, Gregg for German.)
