As someone who is left handed I always had a hard time keeping the flow of cursive writing going while trying not to smear what I was writing. As soon as cursive was no longer required in school I opted instead for all caps, all the time because I can better control what I am writing and I like the aesthetic. Unfortunately when I write quickly some of the letters such as A, D, O, P, R devolve into lesser forms and start to look alike. Maybe it's a subconscious optimization?
