Well, it's the middle of the night, so everyone's asleep, and I just heard a loud "thunk." That means either Mom or Tommy is up, there are burglars in the house (which has never happened before), or my brother fell off of the bed again. That happens a lot. He's a violent sleeper.
Edit- Starting to get a little freaked out now... Could possibly be hearing soft voices outside in the hallway or downstairs? *hates being the only one awake* *can't watch scary movies without not sleeping for a week or more*
