She had to get moving
Because of the uncertainty surrounding her father’s top-secret project, she was acutely aware of the urgency with which she needed to act. She was confident that he would feel bad about Abby tripping on a nail at work, therefore she anticipated that he would be changing jobs within the following two days.
Waiting till Friday
Abby was aware that every Friday, her dad would have a couple beers to relax with. And without fail, each time he did so, he promptly dozed off, even falling asleep in front of the television on occasion. As a direct consequence of this, she was prepared by Friday. She pretended to be asleep when her clock read 00:00, and then she quietly entered her parent’s bedroom while keeping a low profile.
