What happened to Kitty's mother?
They had this whole story line of Kitty's parents coming to live with the Formans because Kitty's father had lost all of their money in a bad investment, then Kitty's father dies, and then there's an episode where Kitty's mother is driving Kitty crazy. After that, the mother was never mentioned again!
This positively infantile preoccupation with bosoms!Terry-Thomas about US 1963.Hasnt changed much!
