Scenario 9-2 You Go to Your School Computer Lab to Write a Write

Scenario 9-2
You go to your school computer lab to write a term paper for a class. Before you start, you play a few games of solitaire. Then, you decide that maybe you should check your email before you get to work. You have several messages, which you answer. You look at the clock, and about an hour has passed since you arrived. Since you're already logged on, you decide to check out the latest posts on a few music websites. Another 45 minutes have gone by.
Finally, you head out on the Web for a few minutes, just to get your brain going and maybe pick up a piece of information or two that you can work into your term paper. But first, you take a cybertour of Graceland, stop by Coupons Online and print out a coupon for your favorite brand of frozen pizza, solve a murder mystery, and submit a haiku about Spam to a site that already has more than 1,500 of them.
It's time to get down to work. You click over to a search engine to run a few keywords on your project. As you're doing it, the lab monitor says it's closing time. You look up at the clock--two more hours had gone by while you were on the Web. You leave the lab grumbling how inefficient computers are, seeing as you never seem to get much done working on them.
