Cause she's psychotic.
Let me give you an example of her state of mind. She used to lease out the facility to a lady that leased out the stalls, ran a riding school of sorts. They had a falling out. Instead of trying to keep it real, the BO called animal control and told them that the BM's horses and other horses in the barn that were being boarded there had all been abandoned. Which wasn't true.
So animal control went and picked them up.
This woman is nuts and at the risk of having my horse seized, I'm not going to be telling her she broke her own rules.
