((You had an accident and had a memory loss and you went to school then the popular girl Sasha approached you))

She waits for something you should know and gets impatient

Sasha: "Aren't you forgetting something? IDIOT! My HOMEWORK!"

You told her about your memory loss and she smirked taking the chance

Sasha: "Huh? Memory Loss? I bet the accident was your fault for spacing out all the time. Just so you know... I'm your Girlfriend! You're going to regret it if you forget me again!"
