Hello!
Hello, Lucy. This is John. Could you do me a favor? I've tried to phone my wife six times and I can't get through. The line is busy all the time. Could you possibly go next door and give her a message?
Sure! What do you want to tell Mary?
Could you just say I've met an old friend and I'm staying with him? I'm not in the office now and I'll give her a ring later.
Sure, I'll go right now.
Thanks a lot, Lucy.
