So last night at around 11, I heard a door creak in the kitchen part ( I was in that area) the bedrooms are on the other side of the house so I thought someone was in the house. I grabbed 2 kitchen knives from the kinfe holder and started to cautiously approach the site of the sound. I pulled the door open, and it was my dad, who somehow got all the way to the study room without me hearing him. I'm an idiot.
