"Hi, can I speak to Jennifer?" the caller said to me. "You've just missed her. She's popped out to the shops for something."
"Are you sure she's out?" "I'm positive," I said. "You know who this is, don't you?" "Actually, I don't."
"You don't recognise my voice?" "Can't say that I do."
"Listen, will you just put Jennifer on, I know she's there," said the increasingly agitated caller. "You don't know anything, and if you call again I'll report you to the police."
"Police! You buffoon!" she said, slamming the phone down. Mother-in-laws, eh? What are they like!
