Jacko's familiar growl, then the front door slammed shut. Michael shivered and pulled the thin blanket closer around his shoulders. Through the cracked glass of the curtainless window, the sky looked gray and dirty. A groan from the other mattress told him that Toby was awake as well.
What can you infer about Jacko's mood?
