Answer 1

When I was young I used to play loads of PC games. So in order to stop me from playing games during my study time my mother would take the mouse away and thought I won't be able to use the computer. At first it was very difficult for me to still use the computer without mouse during my study time.

So I learned how to use keyboard and learned the shortcuts to be able to use just the keyboard instead but then also I had to limit myself to certain games, which were enabled to play only with keyboard. When my mother got to learn about this. She took my keyboard as well.
