*POP* No power.
True to form, my first thought was for my computer. I hear something outside, and step out. No one around...but I see power on, further down the building. 'Da heck? Back inside...about to call Dianna, have her get hold of the power company, when, for some reason, I flipped the kitchen light switch. Lights...hmm, well, OK, power's back, right? No. Turns out, I'd just tripped a breaker. No harm done, other than having to reset my VCR clock. Best I can figure is that it didn't like having both small heaters running at once, which I should have guessed.
