Why?!

WHY?!
“Beep! Beep! Beep!” “Shut up!” I scream at my little brother, Daylynn, who is sitting on the floor playing with his toy cars. “Leave him alone Agnetha he’s only four” Mother calls from the kitchen. “Then tell him to go in his room and play. I have a big test in two days and I need to study.” I yell. “And don’t call me that my name is Agnethaya.” Mother walks in the living room. “Okay ‘Agnethaya’ why don’t you go study in your room. “Because-“ She cuts me off. “It wasn’t a question.” “Whatever.” I roll my eyes and stand up and go to my room. “I hate it here. I hope you all would just die!” I yell and slam my door.
After an hour and a half of studying, I walk out of my room, head pounding like a drum, and go to the kitchen to look for Mother. It’s empty. I walk out of the kitchen and go to Daylynn’s room. He’s not there. Then I walk into living room, Mother’s room, even the basement. Nothing. I go to my room and grab my phone off my bed and text Mother “Where are you????” No reply. “Whatever she probably went to the store with Daylynn and didn’t tell me.” So I go back into the kitchen to grab my keys to my yellow Corvette and leave the house. I walk to my car and get in. Then I head to the mall.
