I must've had a really fitful sleep and been fretting about not winning the lottery, because apparently I was talking in my sleep. When I woke up this morning, my husband asked if I remembered asking him about the plywood. I didn't.
Apparently I was telling him that I needed a bunch of 8x4 plywood. Except, he said, that you would normally want to say "4x8." I looked at him and asked exactly how big is a normal sheet of plywood. He replied, "Four-buh-eight."
Weird. I have no idea how I knew that in my sleep, because if you asked me any other time, I wouldn't be able to tell you.
