Jack: What's your favorite day in a week? 
Linda: I like Wednesday best. 
Jack: Why? 
Linda: Because I like singing, and we have a music lesson on Wednesdays. I can sing and listen to many sweet songs in music class. Music is one of my favorite lessons. 
Jack: I don't like music so much. I like sports more. PE is my favorite subject. 
Linda: Is Friday your favorite day? 
Jack: I like Friday, but I prefer Sunday to Friday. Because I have no lesson on Sundays. 
Linda: I agree with you.
