Re: I'm sure we've all done this too
My ex-wife had the exact opposite effect. I had a small rack of computers in my home office, and by rack I mean a dent and ding wooden shelving thing from Ikea. It had a Sun SS10, MAC G4 tower, 1 or 2 PC clones depending on what I was up to, and a rather large rack mount UPS underneath. If she walked with in 5´ of the rack at least one of them would crash. Usually the PC, but more often than can be attributed to chance, the Mac and SparcStation as well. After all 3 crashed 2 or 3 times when she walked too close I had to tell her not to get within 10´ It wasn’t just computers either.
Lightbulbs had a real bad habit of burning out just as she walked under them, any incandescent bulb in any room and other peoples houses. It seemed to be tied to her mood as well. The more upset she was and in particular the more angry, the stronger the effect would get.
