Recently, I tried to reason with Watchcat Collette. When she kept meowing and leading me over to the room where I keep the cat food, I told her, "Look, you just had a full meal. I know that because I gave it to you. You'll get another meal and a snack later, but it isn't time for that yet."
For some reason, that didn't deter Collette from making her case more insistently. Eventually, I gave in and let her have a small snack.
So much for irrefutable logic.
