Ray: We're not going to get a better offer than that. If you .......... my advice, you'll accept it.
Dave: I'm not so sure. If we .......... a few more days, I think we'll get other offers.
Ray: Perhaps you are right. If you .......... , I'll tell Jagger that we need time to think it over. When he .......... that, he'll be a bit impatient but I'm sure that if I .......... to him sweetly enough he'll hold on and not look elsewhere. If things are looking a bit dicey, I .......... to you.
Dave: So, if I .......... from you, I'll assume everything is fine.
Ray: Yep. I'll only call you if I .......... there is a problem.
Dave: So unless I .......... from you, I .......... no need to worry.
