I unloaded the dishwasher and was getting ready to zap myself a burrito when I looked on the floor and saw it: a drop of water. There was a drop of water on my new floor. Water, the toxic substance to Pergo.
I grabbed the nearest dry rag and wiped it up immediately.
I also swept the floor. Twice. I saw that there was still sawdust in some spots, so swept it up. Then saw I'd missed some other spots so swept it again...and feel somewhat guilty that I had seen a few Sheila hairs on the floor in the front hall, but haven't swept them up yet.
Mark this day. A month from now I will be a lot less conscientious about all this.
