Silly sister & brother

"Kid, can I speak to your mother?" she asked him. 

Zhi Yuewei became even more suspicious. After a visit from the man who claimed to be his biological father, all strangers were unwelcome to his house.

"My mother is not here." he said. 

He tried to close the door immediately after saying that but Alix would not let him. She smiled and stopped the door from closing with only one hand. 

Zhi Yuewei exerted as much force as he could in his attempt to close the door but it did not budge. He looked at Alix in shock, doubting himself and her at the same time. How could she be this freakishly strong? Unless he was the weak one. 

"You__, you___." he stammered. "I am calling the police." He turned his head around and yelled, "Mother, call the police."
