This mistake was mistakier
I am lying on my bed and I notice that the annoying black and white cat (to be distinguished from the many other b&w cats in the neighbourhood) is in my window. What are you doing in my house, cat? And then I look and see that my back door is shut, which means that the cat has been here for, at the very least, 8 hours. May still be here, because I have no idea where the irritating thing got to, because I figured he wandered in through an open door. Which, granted, he did, but not recently.
I am distinctly more annoyed by this than any of the other cats.
