If you can’t manage to say Peter's name correctly then you could try conversing by email. This may be your best bet anyway. In fact, his work phone is equipped with a recorded message that advises this and you could find he answers email faster than his phone. Or not. You can be sure that he will not answer either if he is in the middle of a hang-gliding flight. But we are getting rather too far away from the original topic here.
I had best stop before I incur one of Peter's random threats to divorce me. Mind you, I don’t take these terribly seriously as they occur in response to the most trivial of events. Our son Tristan has taken to threatening us with similar consequences if we fail to provide him with sufficient computer or television watching time. I rate his complaints as the graver threat.
