Mystery behind the secret door

The return of Alexander

Agatha woke up early in the morning to get ready for school, she brushed her teeth and took her bath and was about to dress up for school and that was when the weird voice came
"Can I give you a description of what to wear"the weird voice said and that made Agatha feel like she is getting insane and the voice came again and Agatha decided to do what the weird voice said to know if the weird voice would stop talking, she went to her mom's room and took her pink trousers that was obviously bigger than her then she went back to her room and took her baby pink skinny top with long sleeves, then a jacket that is shorter than the top by about two inches and she was ready to go, she went down stairs and took her breakfast and left for school
"Wow"Billy said immediately he saw Agatha walking into the class and as she passed him
"Close your demn mouth"Agatha said and that made Billy shocked, even Agatha was shocked her self
"See who we have here, the orphan"Angela said
"Shut up if you don't want your mouth to be pulled off"Agatha warned
"I love your new style"Nora said
"Thanks"Agatha said with a smile and sat down and Agatha suddenly started feeling dizzy and fainted and the next thing that she saw was Alexander standing right behind her
"Am back SIS"Alexander said and offered Agatha her hand to get up, Agatha stood up and hugged Alexander and asked her where she have been and she said that it is a story for another day that she is soo tired
