You know you've been in Iraq too long...

• When mortars land near your compound and you roll over in bed and think "still way off, I got another 5 minutes."
  
  
• When you start humming with the Arabic song playing on the radio on the shuttle bus.
  
  
• When you start picturing your wife in traditional Arab dress.
  
  
• When you can put your body armor and helmet on in the dark in under five seconds.
  
  
• When you start to enjoy the rocking of the trailer every time the MEDEVAC choppers fly over.
  
  
• When you're thinking of buying real estate in the Green Zone.
  
  
• When you plan on removing all trees and grass in your yard when you get home so it will look more natural.
  
  
• When you have noticed a change of season - from long, hot and dry to short, cold and wet.
  
  
• When you end every phone conversation with, "Out."
  
  
• When you see an indirect fire attack take out an air conditioner and your vigor to fight is renewed.
  
  
• When you go to a social gathering and intermittent gun fire or explosions don't even cause a pause in the conversation.
