"I made up a story about school inventions once, the school was just three large halls, and a shower block. One of the halls contained touch screens. There were six teachers who would sit had touch screens on their desks so they could send work and virtual lessons to the pupils. You could write with a touch screen pen and when you had finished your work, you sent it back to your Class Head."
