Renos Ohnoes!

So in the process of de-Kening my main bathroom last night, I did significant damage to the old floor. I am very sad.
I really hope that a) businesses that market hardwood floor repair actually provide it, or b) that I can invent hardwood floor repair.
Also, I have a new source of horror: that moment when you, having removed some floor from your second storey and gone to have a cup of tea, hear THUMP THUMP above your head in the kitchen, and you realize that this THUMP THUMP is exactly what you imagined it would sound like if your cat was exploring your ceiling cavity.
