[Don't worry Grandma very soon I will show you that I have the ability and guts to take revenge. I won't disappoint you when that time comes so look forward to it because it will be my turn to laugh]
Joanna clenched her fist. She controlled her inner self which wanted to challenge them.
"What the hell are you still waiting for?" She shouted as if she didn't know that Joanna was there all this time.
"Get in there and prepare me some good food," She commanded.
With gritted teeth, Joanna bent and carried the tray. She spun and was about to exit the room when Grandma Cora's words caused her to stop in her tracks.
"If you make me wait more than the stipulated time, I promise that tonight will be the day I finally put an end to your miserable life," Grandma Cora threatened.
"I will make sure that doesn't happen," she replied and left in an instant.
She could hear their laughter even though she was far away from their room.
