You decide to modify Emily's personality. You weren't really sure what to change... you liked that you had a bud you could hang out with at home.
Suddenly there's a knock on the door.
"Hey, bro, do you wanna catch the NBA game tonight?" Emily asked.
The shock of her voice caused you to pull the personality folder completely out of her drawer.
"Uh, yeah, sorry, give me a sec." You said as you set the folder on the cabinet.
You quickly clean up a bit and open the door to talk to Emily.
On the other side of the door, your sister was standing neutrally with no emotion on her face, staring straight ahead.
"Uh, Emily? Are you okay?" You asked.
She nodded.
"Yes. I am currently feeling well." She answered with a completely flat affect.
You waved your hand in front of her face. She didn't react.
"Would you like to sit down?" You asked.
"Yes, sitting would conserve my energy." She said as she walked past you and sat on your bed.
You looked at her quizzically and then looked at the cabinet. You realized that you hadn't actually put away her personality file back into her drawer. You weren't sure how exactly it worked, but you guessed that when you closed her drawer she "updated" in accordance with her new drawer. And you had just completely eliminated her personality. At least her memories were fine...
You paced. Emily's eyes followed you.
"Do you like sports, Emily?" You asked.
"I do not like or dislike anything. Everything is the same for me." She answered.
"Did you like sports?" You asked.
"Yes, I used to enjoy sports." Emily asked truthfully, "I was looking forward to watching the Miami Heat tonight. Now I do not care."
"Doesn't that bother you?" You asked.
"No. Nothing bothers me." She answered.
Huh, well your sister was now essentially an emotionless robot. You looked her over, one of her tank top straps drooped lazily down her shoulder. You could see the outline of her breasts in her sports bra. She was pretty hot. You could do essentially anything to her, now.
