On a train, you overhear a woman phoning her office. Why has she phoned?

Woman:  Jenny, hi, it’s me. I’m on the train and it’s stuck somewhere just outside the station -- signalling problems or something ...Yes, I know, sorry, but there’s nothing I can do about it. Anyway, listen, could you check my diary and see when I’m supposed to be with those marketing people ... it’s on my desk  ...... Oh, isn’t it? Oh, that’s strange. And it’s not in the drawer? I wonder ... Oh, I know, I must have left it in Jimmie’s office after yesterday’s meeting. You couldn’t get it and then ring me back, could you? Sorry to be a nuisance.

Man:  I love deep-sea diving. I go at least once every summer. The deeper you go,the quieter everything becomes, until finally all you can hear is the sound of your own heartbeat. It’s my way of getting away from it all, finding some peace for once. I spent my honeymoon diving, although my wife’s not so keen, and it’s not something we always do together. I don’t need company necessarily, and I’m not looking for some incredible adventure. I did, however’, once join some guys in a cage off Florida, searching for the great white shark. If sharks stop moving, they die. That sounds like me back home.
