It all started when my friend texted me and asked to sleep over. I texted her back and said "yeah but your mom has to bring you" so she said ok see you in an hour. An hour passed and the doorbell rang, so I looked out the window and Mary was standing there. I opend the door and she came in and then she put her stuff down. After her mom left we started watching a movie and that's when my mom walked out and said she had to go out to get food so we said okay. 20 minutes later after my mom left we herd a big bang in the basement. Mary said let's go check it out and then we herd the bang again so we ran into my room and shut the door.
