Green. She was very good cook and often
made for delicious cakes. The children could smell
them. "How can you get some cakes?" Daniel said to Lisa,
"We can't go and ask for some. That does not seem politely."
"I know which to do," Lisa said. "Come with me." Then
they went Mrs. Green's house. Lisa knocked at the door

with us?" She laughed and asking, "What game do you
want to play?" "We want to play 'At a zoo'. We are
animals and you are the keeper who feed us with your
cakes. All right? "
