One last wish

What if?

"I understand you have been going through a lot recently but I'm afraid this is just not acceptable in any shape or form" the
headteacher said.
"Can I just please explain", I replied.
"I've heard enough, now head to period 4 please and I will speak to you tomorrow when we have sorted something out!", she said whilst opening the door, pointing at the stairs.
I ran into the toilets, wiping my eyes, my eyeliner smudging.
"Who is that?" Asked a high pitched voice.
"Jess Gleem", I replied. "Who are you?"
"It's me", they replied.
I opened the cubicle door to find Flora stood outside. She was the new girl and was often extremely lonely.
"Hi", I said awkwardly.
"Are you alright".
"Yeah"
"Good, good", she replied, nodding her head.
No one really liked her and she often skipped lessons, lurking around the bins or in the toilets. She had big, bright green eyes and hair that was in the middle of brown and red.
"Well as long as you're ok, I guess I can go", she said.
"Yeah you do that", I replied.
"Bye", she said.
I nodded my head, smiling. The lights in the toilets flickered on and off, and the door swung open. I ran into the cubicle, keeping the door open slightly. In front of the mirror was a girl just like my sister, she died a few months a go in a car accident. Her hair fell the same and she was wearing the exact same hoodie.
"Sasha, is that you", I said expecting it to be someone else.
They lifted their hood and climbed out of the open window.
"No, wait, please, I know it's you", I shouted.
They jumped, and landed safely on their feet. They ran fast down the school drive. What is that's my sister, I thought. It can't have been!
