I know exactly how you feel.
Sometimes when I am at a friend's house their parents ask me: "Oh, while you are here can you check why the scanner isn't working and why my email only works sometimes" at that point I feel like screaming because I am not their personal IT support.

My dad can't find a program if it is not on the desktop or on the start menu. He also thinks that his 20 gig hard drive is big enough for modern programs for running a business (it has 36 KB free space at this moment) He doesn't want to buy a new pc for next to nothing he wants to upgrade a 8 year old PC with a new hard drive

My sister can't figure out how to connect to the internet when all you have to do is click connect at the bottom right of the screen.

I get called a few times a day to fix something that's not broke by someone in my house, so I'm fed up with all this.
