He was deceiving them both
This piqued Abby’s interest, prompting her to look into the topic more. Her father had lied to her mother in addition to lying to her. She eventually discovered that her father had lied to both of them. She slipped out of her room in the middle of the night and made her way to the room where her parents were sleeping, where she was surprised to find her mother still there.
Because she was anxious about her mother being there, she decided to participate in these activities. After that, Abby quietly exited the house through the rear entrance and made her way down the stairs.
Learned from her mistake
She had learned from her past mistake, so she made an effort to prevent repeating it by making sure the door did not close behind her this time. She had learned from her earlier blunder and made attempts to prevent it from happening again. There was little proof that she had done any of those things after successfully avoiding detection and then softly closing the door behind her.
After coming to a momentary halt, she continued walking in the direction of the shed after checking to see if her father had comprehended what she was going to say in the subsequent line.
