A blonde went to work...

A blonde went to work one day. She made her lunch and grabbed her keys. She locked the door and then left. After going into her car, 5 minutes later, she had arrived  at work. 7 Hours later she returned home. When she got there, she droped her keys in shock as she peered into her house. She phoned the police saying "Get down here quick! Somthing terrible has happened!" So 2 minutes later the police arived. They took picutres of her house and a police Officer asked her questions."Did you lock the door?" She replied,"Yes! Yes! I locked the door!" He looks up at her and says, "Did you close the door after locking the door?" The blonde did nothing but stand there speechless.
