Part 1 of my first story :)

Well, before I start my story, let me introduce myself. My name is Ayanna, I'm 14, and I'm in the 9th grade. Now that we got that over with, let's go on to the story. Ok, I'm letting you guys know now: I'm a beginner here, so this story may not be great, ok? If there's anything you want me to change or improve on, just comment, ok? No pressure :) Here goes!
*Part 1*
My name is Amina. I have blond hair and green eyes, and a twin sister named Ava. We look the same, but our personalities are very different. She's more mischievous than I am. Anyway, we were walking home on a dark and stormy night, trying to meet our mother's curfew of 10:00. All of a sudden, someone comes on his bike and almost knocks us over! "Watch where you're going, jerk!" Ava shouts. Then, we pick up the things we dropped and hurry home. When we get there, we tell our mom what happened and she said, "The experience would've gone better if he had apologized. Sweethearts, I can't do anything about it. It's up to you two to resolve the conflict, ok? See if you see him at school tomorrow." I think, "Well, today went well." Just then, Ava bursts in complaining about something I don't care about and am too tired to care about. I drift off to sleep, thinking about the guy who almost ran us over.
*Ok, you guys, that's the end for today because I'm too sleepy to continue. I'll probably write part 2 tomorrow, ok? Bye! :D*
