The lost me

Alisa - Hey Laura ! Hey, can't you hear me ? Oh, god this girl and her earphones ! All the time ! Uffffff (This is a character called Alisa, someone who plays a very vital role in Laura's life ) Laura - Is someone calling me ? Aaahhhh no. I might just be hearing things there is no one out here . Laura enters school, and she is late, but she is not worried because she knows her teacher is going to taunt her about whether she is late or not . So she is the one who least cares about her late arrival and enters the classroom. The teacher says "Here comes our queen as usual. What do you think about yourself ? " But still Laura doesn't care and sits in her place . She takes off her earphones and says " Yes mam , did you say something . Sorry I couldn't hear you ." Everyone is shocked to see her behavior but they remain quiet . But Alisa starts yelling at her . "Why do you have to be like this Laura ? Why do you find trouble for yourself ? Oh my girl , stop doing this to yourself . " Laura asks Alisa to shut up Her teacher asks whom are you asking to shut up Laura then she says no one mam Alisa is just seen by Laura after an incident. She stays with Laura all the time but is she her imagination or her health condition .
