Calming Melody, I agree with you. A dishonest person will always be a dishonest person and the fact that the OP had even thought about this enough to consider asking about it speaks great volumes about her integrity....or lack thereof.
Janna, we open our hearts and there's always someone who will stomp on it. Perhaps the owners are too busy to visit the horses yet they must feel confident they are ok at your place. If you continue to pick up the slack, they won't. I hope your chat with the owners turns out favourably.
I just gave away a 2 year old mare that someone brought here in Dec to have me work with and board.
He was supposed to do work aroung the farm for payment.
He showed up about 4 times.
The mare had never had a shot, her feet trimmed or was halter broken.
At the first of March she foaled a colt that was stillborn.
I called the vet to make sure she was alright and that whatever it was would not infect my horses.
He demanded his horse back and even showed up witha trailer .
I told him to get off my property and to bring me 1500$ for upkeep vet bill, and board.
I just got this mare back from having her trained and gave her away to a good home.
He did show up with a sherrif who told him it was a civil matter and that since I had no trespassing signs he could not just walk into my pasture and get the horse. Shalom
