Don't get confused by the title: Simple and short: My sister for some reason can't write properly (alignment, neatness), if she doesn't turn her book horizontally. I've been forcing her to practice working with the book vertically but she's struggling and the writing is coming out sloppy. Is there some kind of condition / disease / disorder behind this? Or is it because she has been doing it for so long she is used to turning the book? Will about 2 weeks of writing "normally" make her adjust and write properly with the book vertically on the desk?
