Rivkah is trying hard to get the tomato ketchup to come out of the bottle. As she is banging the bottom of the bottle the phone rings, so she asks her four-year-old Faye to answer it.
“Mummy, it’s the rabbi,” shouts Faye. But before Rivkah can get to the phone, Faye says to the rabbi, “My mummy can’t come to the phone to talk to you right now. She’s hitting the bottle.”
