But I will definitely be purchasing! Jess, how do lawyers feel about Oxford commas and double spacing at the beginning of sentences? I've noticed some lawyers using double spacing in their communication to me so wondering whether or not I should be using it in the context of a written assessment...
As for the Oxford comma, I wasn't really taught it - or barely other grammar rules - at school. I can see why it makes sense. Is it a big deal for lawyers?
Lastly, are some punctuations, such as a dash or exclamation marks, seen as informal in written communication between trainees and their teams, or trainees and clients?
