Have a ball when agents don't show!

Frustrated not knowing if the agent who scheduled the appointment actually showed up? Here's a little trick to discover if anyone has been inside your house.

Before you leave the house, place a ball up against the door the agent will enter. When the agent  opens the door, the ball will roll away. If the ball is in its original place when you return, you know no one entered the house. Even if the agent  knew exactly where the ball was originally placed, it would be impossible to replace it to its beginning location.
