As soon as you deal with more than one computer, you need to

problems that people stumble over again and again.

Conversations would sound like this: "Is up down?" and "Boot
the machine up." followed by "Which machine?"
While it didn't take long to catch on and get used to this
zaniness, it was annoying when occasionally your mind would
stumble, and you would have to stop...
