Computers Know You Are a Newbie
I believe computers are not as lifeless as a machine. They play tricks on people's minds. They are notorious in the way they frustrate people who are new to computers or a task. I have experienced this scenario many times, on both ends:
A: "Hey, come here. I can't make this work."
B: (Comes over) "What is it?"
A: "I just did X, and then I did Y. I should get Z, but I did not."
B: "Show me again."
A: (Does X, and then Y, and gets Z) "Oh well, it worked this time. Thank you anyway."
