You hear a knock at the door. Your new tail still wagging behind you, and the glove still stuck to your hand, this couldn't have come at a worse time. "I'm busy!" you shout, hoping it'll be enough to drive whoever it is away while you quickly rush to get a housecoat on to try and hide the tail under it. Unfortunately, it's not, and you hear the door open and then slam shut, loud footsteps trudging their way down the hall and growing closer. When she gets in the room, you realize that things just got worse: it's Lisa.
"Oh, you're busy huh? Busy?! Who the HELL do you think you are?!" The force of her screaming alone is enough to knock you backwards into a chair, landing painfully on your tail. It hurts enough to make you cringe, but Lisa just assumes that it's because you don't want to deal with her right now. "So this is how you treat your friends, is it? It's all good as long as you get something out of it, but the second you don't you want them gone? You shallow, self-serving bastard!" So far, so good - you almost want to sigh in relief that she hasn't used any words that might set off the glove so far, but given that she's still talking that would be a mistake. Unfortunately, she picks up on your relief, and again she misinterprets it. "Oh, I'm sorry, is this not serious to you? You find this funny or something? So what, you think you can treat people like total shit, and they won't do anything about it?! Well, I've had enough! Screw you, you fucking horse's ass!"
Ooh, so close. She finally leaves you be, storming out of your house with the fury of at least ten women scorned, but right now you have bigger things to worry about. Once again, your friend has spoken one of the command phrases, and once again, you're left to either think of something quick or be stuck with a chunk of animal for the rest of your life (and a horse's ass probably won't be any easier to hide than a dog's tail).
