Please Hold. Your Call is Important to Us.

Please hold. Your call is important to us.
My mother recently decided that she had a telepathic connection to my sister, Claire. Unfortunately, she failed to make this known in advance. Claire started to get plaintive, sometimes downright annoyed, voicemail messages.
‘I was standing in your bedroom willing you to call, and you didn’t. Where are you?’
She doesn’t try it with me, probably because my horror of the telephone would waste her time. But I don’t know whether to wear a protective saucepan or a satellite dish on my head, just in case.
