This is not even the hardest part; the hardest part is that the wet nurse and the cousin just can't get along. Whenever they meet, no matter how much the cousin tries to yield, the wet nurse just finds her objectionable, openly chastising her as hypocritical, pretentious, insincere, and so on. It's bad enough that she says these things, but she also insists on agreement, leaving herself stuck in the middle, fed up like a mouse in a bellows.
Letting her go home to enjoy her old age in comfort wouldn't be too bad.
"You're right, the wet nurse should indeed go home and enjoy some peace, but," Shi Fengju said with a smile towards Gu Fangzi, half-joking, half-serious: "You've never gotten along with the wet nurse, why do you suddenly speak up for her? This is not like you!"
She has always been clear about her grudges and affections, resolute and straightforward; how could she be speaking up for the wet nurse?
