Ok heres the scoop . We entered into a lease agreement and recently found out that our landlord has been using our electricity to run his shop on the property . It was never stated in the agreement that it would be this way . They landlord did say that her son used the shop still but she didn't mention they would be there at all hours of the day and night . 
Question: What's a possible reason the landlord has been using the writer's electricity to run his shop on the property ?
Because the landlord is a thief .
