Yeah we both did it wrong...
"Elia, come down!" dad yelled, and I hurried down the stairs. "Ellie, I have to tell you something honey. I'm not your real dad."
"What!" I shreiked.
"I found you when you were little and decided to keep you since you had no parents. We found your parents, you mom is dead.... and your dad is married to another woman and has a daughter the same age as you." I felt my heart about to burst. "The girl's name is Malia and I think she goes to school with you.
At school I manage to get detention 5 times, my anger fueling me. Before detention I quickly slip into the administrators office and erase all the grades, now I'm happy.
I heard Mal, my half-sister! talking about her future plans. "And when do you plan on doing that?" I ask as I walk in.
"I may have already done that on the way here" she said just before the principal walked in the door.
"Whoever did this is in detention for the next three weeks." the principal said, yes!
"Great, I'll be there." Mal says triumphentaly.
"Don't bet on it sis," I mutter. "What for?" I ask.
"For erasing all school records of course," she says.
Everyone gasps as I announce it was me. "Oh, Mal, your in detention for two weeks to for gluing up my office door," then she leaves.
"Okay, losers, out of here," everyone leaves except Grim and Mal who's still in tells him to go. "Mal, my da-fake dad told me, your my half-sister."
