Recently, a teenager waved me over to the computer on which she was working and asked for my help in accessing her PowerPoint presentation.  Thinking that she had never before created a PowerPoint, I was preparing to walk her through it.  However, her problem was not what I expected.  She opened up the PowerPoint program, and then asked me where hers was.  Baffled, I asked what she had saved the document on, i.e. a floppy, a CD, or a flash drive.  She gave me a blank look, and finally answered, “I saved it on the computer at school.”
