@Mame,
You took a neighbor or a relative to buy an expensive computer she probably didn't need and doesn't know how to use. Helped her take the computer home and "set it up." Told her it didn't work and that you'd get it fixed. Took the computer home with you, now you're using her new computer instead of your own junkie virus riddled computer and if she ever asks about it you say it's still getting repaired. Sound about right?
I'm dressing up as a scientist from a video game this Halloween to go and watch the famous Village Voice Halloween Parade this year.
