There's a section of our parking lot that is single lane (divided each direction) with no room to pass. It's not a big deal, except if you're late for work and get stuck behind the duck. Especially if it's the duck with an attitude. Honking just earns you a glare from the bird. Yelling "Duck! Duck! Duck!" out the window earns you a glare from the neighbors. (And I really was just yelling "duck!")
Normal ducks would try to get out of the way of a heavy, noisy car with a cranky, late-for-work driver. Those sensible ducks would realize that walking down the middle of the drive with the car inching closer and closer is not a good idea, and they would hurry to get out of the road.
Our duck, however, reacted by going even slower and slower as he walked down the entire length of the drive.
So why did the duck (finally) cross the road?
To get in the way of another driver, coming up the drive!
