I appreciate all the sympathy, and yeah, I'm going to talk to her about why she did not at least pick it up.
That said, please don't be to quick to judge someone you don't know. She is a night nurse who works her ass off, doesn't get the rest she needs, and her first half hour of being awake is pretty much in a haze of semiconciousness.
The razor was covered up by a towel, so I can't really fault her for picking up the towel which dragged the razor off the counter. I can fault her for not picking it up or telling me she dropped it.
