That squeal gets louder as you walk up the steps.  You are heading down the hall.  When you get to your brother's door, the squeal becomes as loud as a dog barking.  You open your brotherís door and you find his hampster stuck under the hampster wheel, trying to get out by calling for help.  After you help the hampster out from under the wheel, you hear a roar as loud as a freight train.  Then your mind turns on and that roar is your parentís car driving down the street.

You decide to call your mom's cell phone.

You decide to walk to your friend's.
