dialogue: W: Is that your dog? He's not very friendly. M: Yeah, that's Sammy. I'm sorry he's a little anxious. He's usually quite playful, but he had a rough day. W: How does a dog have a rough day? Don't they just chase rabbits and sleep? M: Well, I took him to a dog park, and a larger dog bit him. I'm worried Sammy will be afraid of strangers forever. W: Well, that explains it. Don't worry about it. Why don't I sit over here on this chair and calm him down? M: Thanks for understanding. I'll get you something to drink. W: Thanks, but I'm sorry I'm early. I really thought the invitation said 7 o'clock. M: That's all right. Most people start dinner parties at 6:30, but mine's an hour later because everyone's going to the football game. W: Oh, dear. I wish I were a fan. I should have known that.
