I learned two space in keyboard classes but hated every second of it. It made no sense. And to a kid who loves to push authority I always asked "Why am I doing this arbitrary thing no-one can give evidence as to why?"
I'm glad two-space died, and I no longer two-space. In my school it was simply used as an authority or power over the children by a typing teacher who was frustrated in a lot of things, but mostly in her marriage.
Mrs. Botana - You were the most hated teacher at our school, and you telling us you recognized how hated you were solved nothing. Enjoy your two-space.
