Ricky: Hi, its me. Are we still going to the concert on Saturday?
Sue: Yeah, fine.
Ricky: Ill pick up the tickets at lunchtime tomorrow. No ... I cant. Ive got choir practice. I know. Ill go and pick them up as soon as school finishes.
Sue: You cant tomorrow. Its early closing. The ticket office closes early.
Ricky: Youre right. Maybe my mum can get them. She works near the ticket office. Ill ask her when she gets back tonight.
Sue: Ive got a better idea, Ricky. Ill go and get them now, before I go to the dentist ...
Ricky: Oh, all right ... but I said ...
Sue: I have to rush, otherwise I wont have time. Byeee.
