Or more like:
This is Aaron's house.
It has five doors, but each one was donated by a different company.
Each company gave Aaron a key, but can opt to change their locks at any time.
Last week, two companies decided to change the locks on their doors.
The didn't tell Aaron. After all....they are only in charge of the doors, not the house.
Suddenly, for no apparent reason, Aaron's family members started complaining they couldn't get into the house any more.
Aaron was confused.....why would this be?
He checked the hinges, the door knobs, the peepholes, and after a week finally realized it was the keys had been changed.
Once Aaron knew this he had to go get two new keys made.
The companies that changed the locks don't care about Aaron's troubles, or that Aaron's family couldn't get into their house for a week.
