The following passage is taken from a novel. Lori is a busy wife, mother and community volunteer. Her father-in-law is preparing to marry Amelia, and therefore both Lori and her husband Bill are busy with the wedding arrangements. Bill’s aunts Honoria and Charlotte (the ‘Harpies’) also offer to help out. In this passage, Bill and Lori discuss the wedding plans.
‘If the Harpies are rude to you,’ he declared, ‘I’ll strangle them.’
‘I should hope so,’ I said lightly, but one glance at my husband’s thunderous expression told me that he was not in the mood for levity. ‘What brought your aunts to mind?’
‘A phone call from Father,’ he replied. ‘Honoria and Charlotte will be arriving at Fairworth House on Monday.’
‘Monday?’ I said, my heart sinking. ‘Why so soon?’
‘They say they’re coming early to help Amelia with the wedding, but you and I know they’ll do nothing but nitpick and nag.’ Bill laughed bitterly. ‘I wouldn’t put it past them to spend the next three weeks trying to talk Father out of marrying Amelia.’
‘Fat chance,’ I said scornfully.
‘“An artist in the family,’” said Bill, mimicking Honoria’s penetrating nasal drawl. ‘“What on earth were you thinking, William? We could understand it if she dabbled. Everyone dabbles. But she sells her paintings. For money. My dear, it simply isn’t done!”’
‘They wouldn’t be stupid enough to talk like that in front of your father, would they?’ I asked incredulously.
‘I almost wish they would,’ said Bill. ‘It’d be a treat to watch Father kick them out of Fairworth.’
‘If they spout off about Amelia, he will,’ I said. ‘And they won’t be able to stay with us because we don’t have a guest room anymore.’
