Smith: Hello. 
John: Hi, Smith. This is John speaking. What are you doing? 
Smith: I'm watching TV with my wife. 
John: Are there only two of you at home? 
Smith: No, my son is feeding fish, and his wife is washing clothes. What about you? 
John: I'm thinking about the weekend party. I'd like you to join us with your wife. Would you like to come? 
Smith: Sure. When and where? 
John: We're going to get together at my home at 9 o'clock this Saturday. 
Smith: Ok, see you later.
