Dog Barking at the Window Washers

This morning when I came in to work I was in a little bit of a funk.  I noticed that the building next to the parking lot was getting its windows washed.  There were two guys on a rig lowered from the roof.  They were six or seven stories up and I could hear a dog barking at them. 

It made me think about how that dog must feel.  Two strange guys banging on the windows.  For all he knows they're trying to bust in and attack.  The dog can't know the bigger picture. 

It reminded me that sometimes fear is just a lack of understanding.  Its very hard to see the bigger picture.  And I'm getting tired of barking.  ;-)
