Let me clarify before this gets confusing, I know both the buyer and the OP. I was helping the OP sell the horse, and passed along his info the buyer, who I had previously sold a horse to. The horse is not, and was never going to, leave the OP until he was paid for. But, and this is what got it all started, is the OP was not wanting to let the horse leave until she felt he was 'well enough'. Which, in itself is fine. But, neither of us know yet when the buyer is having the shipper come pick him up. If the OP keeps kicking dirt and not giving me the "okay, he's ready to start work", I may not have enough time to do anything the buyer needs/wants me to do.
This isn't as a big of a deal as it has been made out to be. IMO, the OP is clinging too tightly and I almost feel as if she will back out of the deal, which will cause me to be irritated with her, the buyer to be out time and money, and me to lose face with the buyer and my friend (the OP).
