I was working with in-office with a client when they came running into my work area.
Client: Help! My computer is being hijacked! Someone logged in somehow while I was working and took over the keyboard. They are typing code into the spreadsheet as I speak.
We rush over to his desk, where the same character is rapidly filling the spreadsheet.
Me: Well, here’s your problem.
I lifted the book weighing on the corner of the keyboard. The hijacking suddenly stopped.
