Billie Burke's voice?

During the scene where one of the children from the Settlement House is talking to her mother on the phone, the mother's voice sounds exactly like Billie Burke - particularly when the mother says "Mummy", just like Billie said it in "Father of the Bride" when she is reminiscing about how her son used to talk when he was little.




"Don't call me 'honey', mac."
"Don't call me 'mac'... HONEY!"
