Jackie is small. Very tiny, in fact. She is so small she has to use a stepladder to get on the chairs in the YS shed. She now writes for Just 17 Magazine, but no one knows why as she is so small she wouldn't even pass for 12, let alone 17.
(Jackie is in fact over six-and-a-half feet tall. She was photographically reduced to avoid intimidating the readers, as she would have appeared constantly with her head out of frame and looked like a spooky ghost.)
