In the early 2000’s I was a PC technician. I would travel to different businesses to help fix hardware problems. On this day, I was called out to replace a simple CD Rom drive on a PC. I arrived onsite and was guided back to a woman’s office. When I entered the woman’s office I realized that the hardest part will be finding the PC. Saying the office was a little messy would be an understatement but at least there was a trail over to the desk. This wasn’t the first messy office I was ever in and from past experiences I learned to find the biggest item attached to the PC which would be the monitor and trace the wires back to find the PC. After finding the PC and replacing the CD Rom drive, I wanted to verify the new drive was working. I had the woman log back into Windows and check to see if the new drive would read a CD. However, I noticed something very odd with how she was using the mouse. The mouse was upside down and she was trying to move the round ball inside the mouse with her finger and struggled to press the mouse buttons. I thought to myself she must be doing it because of the lack of space on the desk. However, when I needed to take control of the mouse to check something I flipped it back over and cleared a spot on the desk. She noticed that I flipped the mouse over and she asked why I was using the mouse upside down. I quickly realized she had no idea that she was using the mouse upside down. I told her that the ball goes against the desk and I showed her how to use it. At this point I had to find out why she was using the mouse upside down. She told me that another pc technician was working on her computer about a year before and he used his finger to move the ball on the mouse and that’s why she thought that was how it should be used. Yes, she was using the mouse incorrectly for at least a year and no one thought to tell her that she wasn’t using it correctly. This is a great example of why you shouldn’t learn by just watching other people but rather ask questions.
