Mary Popins looked at them carefully.At last the woman gave a long loud sniff and said : "All right. I'll stay."
When Mrs. Banks left the Nursery , Jane and Michael came up to Mary Popins.
"How did you come ?" Jane asked. " Did the wind blow you here ?"
"It did," said Mary Poppins and no more. And she gave another sniff and opened her bag.
"What a funny bag " Michael said. There was nothing inside.
But the next moment Mary Poopins took out a white apron,a large cake of soap, a tooth-brush , a packet of hairpins, a bottle of perfume and a small armchair.Jane and Michael were snocked
That Mary Poopins took out a large bottle of medicine.
["It's that your madicine ?" asked Michael.
"No, it's yours , " said Mary Poppins.
" I don't want it " I won't!"
But suddenly Michael understood that he could not say "no" to her. He closed his eyes and opened his mouth.
"Strawberry ice " he said . " More , more , more"
But Mary Poppins, with her cold eyes, came up to Jane.Her spoon was full of something green and yellow.
"Sweet lemon-juice . I love it , " Jane said but when Mary Poppins came to the twins with the bottle,she cried.
"Oh no! It's not good for them.Please!" . But Mary Poppins didn't look at her. She brought the spoon to John's mouth. He drank it and Jane saw there was milk in the spoon!
