Pablo's room was never tidy．He liked to put his things everywhere．Nico's room was always tidy and clean．He liked to organize(整理)everything．
Pablo and Nico had a baby sister one Sunday．⑴
"I don't want to stay in one room with Pablo．"said Nico．
"How can I do anything fun when everything is so clean?"asked Pablo．
"Find a way to work it out．"said their mother．
⑵"It's too clean out there．"he said．But the closet(壁橱)was too dark at night，so Pablo moved back into their room．
In the second week，Nico put some tape(胶条)on the floor(地板)．"You, stay on your side，"said Nico．But Nico had to cross the tape every day to leave the room，so he took the tape away．
In the third week，they thought they needed some rules．
"The first rule is that you can't use my things，”said Pablo.
"The second rule is that you can't use my things," said Nico．
⑶ And at last they thought there was one more thing to do．"We need to paint(用颜料画)in our room!"Lucky for them．they had the same idea about what to paint．
