John: Mum!
Erin: Don't mum me! It is my house and I am not putting up with it being a pig sty!
John: Yeah, but...
Erin: You're grounded unless you clean it up tonight. Pronto!
John: But I'm over at Alex's place tonight!
Erin: I don't care! You heard me! 
John: OK! I heard you.
Erin: Well?
John: I'll do it tonight. I promise!
