At the risk of sounding repetitive, Jack does have nice handwriting
And I think it is rather sweet that she writes in out in long hand with her smol arthritic pixie hands rather than typing it like most people .
What she's saying is that the photo she posted is the notes for the speech she gave, but she went wildly off-script so she's going to "transcribe" everything she uttered yesterday. Because it's really important stuff, obviously.
In Jack's biopic (Ruby thingy playing Jack)it would start off with Jack in a half empty meeting room reading softly, gently, tremulously from her notes.
As her speech continues, the camera pans round to see the room softly, quietly, gently filling up. Jack's voice grows stronger! more confident! Then she flings away the notes and gives an impassioned speech straight from the heart!
Camera pans around again, the room is full! Men in suits and women in Hobbs dresses are crowded round the door jostling for entrance!
Jack's speech draws to a triumphant conclusion. The audience break out in to spontaneous wild applause! And fade.
In real world, Jack makes an illjudged joke about playground bullies, there are a few uncomfortable titters and some mutters "she shouldn't really say that,"
