Universally people don't love to be responsible for themselves or their actions. Equally true is the fact that everyone needs to be right. This evokes mental distress to the point of physical pain for me on a daily basis.
Example one - Laziness:
User: I brought you my laptop to fix on Friday but I didn't bring it out of the car.
Me: Did you bring it with you today?
User: No.
Me: Ok well try to bring it with you tomorrow.
User: Maybe you can buy me a car charger so I can do my work in my car. On my laptop.
Me incredulous: There isn't internet in your car.
User: No, ha ha, but I could send you out there to fix the laptop.
Me: >:(
Example two - Computers are too complex. There are too many buttons. Too much clicking:
User: The photocopier says "BROADCASTING"
Me: So?
User: It never says broadcasting. It also says "Waiting." It never says waiting.
Me: It looks like there is a large job ahead of your job so it's waiting in queue. Let's look at the details of your job to find out why it says broadcast -- oh look, it's being sent to an email and a fax address.
User: No the copier is wrong. It should just be email.
Me: Well that's strange, I wonder how it decided to send it to two addresses?
User: I selected their fax number first, but changed my mind and then pressed the email address.
Me: But you see how that selects 2 destinations? Fax first and then email? Either clear all the accidental selections by using the CLEAR ALL button, or de-select the wrong address and then select the correct address.
User: Why can't it just read my mind?
Example three - This thing won't work. You provided this thing. Therefore it is your fault:
User: I can't make this work, it is falling apart.
Me: You clearly have broken this thing. It looks like you purposefully have used it in an improper manner and/or drop-kicked it.
User: You bought me a bad thing. You should get me a better one.
Me: >:(
Example four - Define catastrophe.
User: I cannot print. I can never print!
Me: You printed yesterday just fine. Here is an error message "Error: Cannot print document." It looks like there are a lot of printing jobs that you started after one that failed. Did you get mad and press print 14 times?
User: You bought me a crappy printer! You should buy me a better one.
Me: This is a good printer. I will restart the printing. See, now it is printing just fine.
User: You bought me a bad printer. You should get me a better one. I consider not being able to print a catastrophe.
Me incredulous: A catastrophe? We have many other printers. Maybe it is an inconvenience to walk 20 steps to the next printer, but this is
not a catastrophe.
