Body-snatching

Gabriella, 19 Yo, was doing her weekly biking in the forest. She loved to ride under trees, smelling humus, saying "hellos" to walkers passing by... until one of them, an old granny, suddenly felt in front of her wheels.
Gabriella braked just in time to not collide the elderly. But she felt herself on the floor.

"Excuse me, miss, are you alright ?!" asked with fear the old woman.

The young girl looked at herself. But fortunately, she just had scratch. So she answered :

"I think it's okay...
- Thank god ! After all, it will be such a shame if I harmed such a beautiful young body"

That's when the elderly lady grabbed her arm. And suddenly, Gabriella felt her head going dizzy. When it finished to turn in her head, she saw someone steal her bike. She tried to purchase the thief but felt her body so heavy and painful.

"Don't try to run or you'll break you something", laughed the robber : Gabriella herself.

As the young girl realized she was now magically into the granny's body, she couldn't do anything to stop the former owner to steal her bike... and her life.
