ACCEPT AND REFUSE INVITATIONS

Jake          Hey, Tina, do you want to go into town after school?
Tina           No. Sorry, Jake, I can't. I've got a maths exam tomorrow.
Jake          Oh, right. That's a pity.
Tina           Yes, I know.
Jake          What about Saturday then? Are you busy?
Tina           No. Why? What are you doing?
Jake          Some of us are meeting at the shopping centre if you
                   want to come.
Tina           Sounds good. I must go now. Text me later,
                   OK?
Jake          OK. Bye, Tina.
