My friends Melissa, Lance, and I were in his basement looking for a game to play because we were really bored. Its always really creepy and quiet in his really clean house. There was a stack of games and boxes on a table by the wall. I decided to try to get the box on the bottom out without knocking the whole pile over. It didnt work. Everything fell. So my friend lance rushed to pick everything up. At the same time we heard what sounded like a guys voice. We thought it was out friend ben and his gf finally coming over. so me and Melissa went upstairs to open the door for them while lance finished picking up the boxes i knocked over. when we got upstairs the door was wide open(and its a hard door to open cuz it gets stuck). We yelled down to lance(we were scaredy cat girls) so he came up. as we shut the basement door we heard the cat toys being rolled around downstairs but the cat had ran up the stairs before us. We then decided to watch movies and the cat kept looking at thin air and following something.
