A: Hey, mum. Could I go out to see the dolphin show this Sunday, please?
B: Sure, you can.  But you have to do some chores first. 
A: What do I have to do?
B: Well, first you could clean your room. 
A: OK. Then what? 
B: Then you could take out the trash. 
A: Yeah. I can do that. 
B:  And you need to feed your dog. 
A: Wow! I'm going to be very tired that day.
B:  I'll help you. 
A:  Thank you.  Mum!
