Mine would be like this:
In the morning: Hey! Let me out! Come on, Pleeeeeeease! Fine, at least give me a cookie or something. No, I don't want regular food, I want the good stuff! You're mean. I'm going to go pout in the tube.
Afternoon: Do you MIND? Someone of us are trying to get some sleep here! I don't care if you have stuff to do, this is my house and it's sleep time! Go away!
Evening: Let. Me. Out. Of. Here. NOW! And hand over the treats while you're at it! You're supposed to do what I say! Fine, you can give me some scritches first THEN let me out of here! Yeah... that's the spot. I'm in heaven. Wait. Why'd you stop? Hey! Where are you going? I said to let me out! No, you can't go upstairs! Get back here! No fair!
He already has an attitude without being able to talk.
