Thanks, V.
Thanks Leigh, for talking me through this little bit of hell tonight.
He keeps changing his story. I keep hearing new details.
So, at this point, he is saying that he made a little fire in our outside firepit a week or two ago, and he burned a bunch of my documents I cleaned out from my filing cabinet, old stuff that needed shredding. Well, while he was doing that, he got the bright idea to put the Dutch oven covered in the extinguisher residue into the fire pit with the papers!! The smell is from the burned documents and the residue. He said that today he returned the Dutch oven and its lid to the kitchen and stored it in the oven. He was going to leave it for me to clean, I know it. He took all of that out of the oven today in order to run the self-cleaning cycle, even though he noticed a strong smell.
