Normal?

Something this crazy seems to occur all the time around here:

• An apartment fire that injured six people on the South Side Wednesday night was set by an angered girlfriend who lit her boyfriend’s couch on fire following an argument, police said.
  
  No arrests have been made, however, the Chicago Police Bomb and Arson squad is investigating the blaze, sparked about 10:35 p.m. on the top floor of a South Shore apartment building, said police News Affairs [...].
  
  Officers called to the scene spoke with an injured man who told them his girlfriend had set his couch on fire after the two had a fight, police said.
  
  Six people, including a child, were injured when heavy flames spread from a single apartment to a hallway of the four-story building at 7102 S. Jeffery Blvd., according to Chicago Fire Department officials.
  

Argument with your man equals "torch the whole building." Yeah, we can see that.
