About ten minutes ago,
Noone hurt, thank goodness, although I think we both set new personal records for heart rate and it may be quite a while before the kitties will go anywhere near the kitchen. I will also not walk through there without shoes on until the floor has been swept, mopped, swept again... you get the idea.
I expect a call back from the warranty people early tomorrow. If we're very lucky, maybe we can get them to replace one or more of the full-spectrum tubes we put in there. We'll see. If necessary I will settle for a light fixture that does not fall down onto the floor, ever.
That was more excitement than I needed in my evening...
