Turning on the lights
When she opened up the basement door, she looked inside to see what was down there before she would enter. It seemed like it was completely empty, so she walked in and started to look for the main light switch. Finally, she found it on the wall that was on the far side of the basement.
She turned the lights on and the entire house lit up. Immediately after she did that she heard something coming from upstairs. It made her jump in fear. She now knew that something was upstairs in the house, and it was probably the cat, at least, that’s what she hoped it was.
