Thanks for all your comments, everyone.
We won't know until tomorrow evening if our counter offer will be accepted or countered again. That's fine by me. I'm planning on sleeping in tomorrow.
It was -19 C tonight on the way home from work. Holy frosty toes. These temperatures have not been kind to my few remaining barnyard critters. R.I.P. Cuddles, Romeo, and Bobsey Twins. I am down to only four chickens.
