How do we know the entire situation if most of it is heresay?
What I mean is, no one but the BO 'witnessed' T handing over ownership. What if that never happened?
What if it wasn't a transfer of ownership but a 'hey could you look after this horse for me' type thing?
There is just not enough fact. I feel since this pony was free and it is gone... and there's a chance of incuring a LOT of lawyer fees... I would put up ads asking for information on the pony's whereabouts and if nothing turns up, I'd honestly look at a different mount through proper adoption/purchase channels.
=/ Not to be a downer, I'd fight tooth and nail for my horse. But yeah... too many loose ends
