MAKE

“Do you want pink?” Mum suggested. Kathy her head.
SHAKE
“No, pink is either for or for silly girls who like Barbie dolls. I’m neither of those.”
BABY
Her parents smiled but anything.
NOT/SAY
“But what colour to choose? I wish we ask a designer for professional advice,” said Kathy.
CAN
“Oh, no! It’s out of the question!” said Kathy’s mother, firmly. A designer’s advice is much than we can afford.”
EXPENSIVE
“Ok. It was just an idea.”

“Getting back to the wall colour, why not make your room yellow or orange?” Dad suggested. “When the walls in those colours, the room will look cheerful.”
PAINT
“Yes!” Kathy definitely liked the idea. “We’ll make three walls yellow, but the one will be orange.”
FOUR
The next day, when Kathy came back from school, her Dad said: “Look what I.” There were paints and brushes on the floor.

“Everything’s ready for us to start.” He smiled and handed Kathy the brush.
