I'm not an expert but have some experience with it. Ruler straight lines: pays attention to detail. Highly pronounced right slant: has a high opinion of herself. (Right slant means self confidence, but this handwriting is extreme) The lack of any flourishes and almost completely non-existant closed curvature letters, like the "e"s and "a"s shows ol' Mama T to be self absorbed and non-nurturing. IMO, of course.
