"Please could I speak to Tilly Floss?"
"I'm sorry, she retired earlier this year."
"But I've just had an email from her."
Guess who won't let me get Tilly's email and PC network accounts deleted because he wants to keep all the emails in Tilly's Outlook folders and won't let anything be done about moving it all to a shared folder.
You can make up all the rest and be very close to the available truths.
