I know what you mean! I was strongly advised against an Arab by my best friend/riding instructor. She went on a week vacation and I found my Basko. He was being advertised as a free lease. I went to meet him and he was starving, a rack of bones, and standing literally in inches of muck in his stall. (He has once been a gorgeous show horse.) He was so pitiful but once he put his head on my shoulder I was SOLD. His owner knew she couldn't afford him anymore.
After about a week the barn owner who was his owner, went to feed him as I was leaving, walking down the driveway. She opened the corral door and instead of running to his stall to scarf down his food as he always did, he ran all the way down the driveway after me!
She immediately started crying and signed him over to me. It was a very emotional and touching experience that I will never forget.
