The andriod knocked on your door, her knock gentle but loud enough for you to hear.

"May I come in?" she asked politely.

She just finished cleaning downstairs, as she was assigned to by Todd, your father. Your sister was Alice, though she wasn't human, she was a child andriod..but Kara didn't know that.

Her eyes wandered the halls for a moment, before turning her attention back to the door, waiting patiently for you to answer. Her LED light was a light blue, showing that she was calm.
