20、“Mary, your bedroom is a mess ．Come and clean it up right now,” her mum said．Mary wanted to go outside and play．“I’ll clean it up later, Mum．”

“Oh no, you won’t．I’ve been asking you for days,” her mum said．

Mary went into her bedroom．She put away all of her clothes and put all the rubbish into a plastic bag．“Mum, I’ve finished,” she smiled, “I’m going outside to play now．”

She ran into the back garden．This was her favorite place to be．A small butterfly flew over and landed on Mary’s hand．“You’re a pretty little butterfly,” Mary said, “Does your mum make you keep your bedroom clean?”

“What if I left my rubbish all over and didn’t keep the garden clean and tidy? Would you have a nice place to sit among the flowers?” said the butterfly．

“I’d not be happy if I came out to see rubbish here and there,” Mary said．

“Everybody has to do their part and keep their rooms or their flower gardens clean,” the butterfly said and then flew away．
