At some point last evening, most of the lights off, I was coming up the stairs, and was meowing at the cat. The cat meowed back, and we were having "a conversation", as you do.
I became aware that the cat was in front of me, but the meowing was coming from further up the stairs.
That's when I realized the cat wasn't saying anything, but my wife and I were meowing at each other, each of us thinking the other was the cat.
Meanwhile, the cat was sitting between us, wondering what these two idiots were talking about.
