Trying to sell my horse

Oh the joy. I am in the process of trying to sell my horse, Tessa. She's my baby but I also want what's best for her and I've just not been able to get to my parents' house to care for and ride her on a regular basis. So now comes the fun part of trying to actually find her a good home. With this recent heat wave there have been more flies which have not only been eating her alive but also causing her to rub the top of her tail and base of her main off. Wonderful represenation of herself and all of her beauty... We've already have a few people proclaim their love and extreme interest and then vanish into thin air. Right now I've got an interaction lined up with a potential buyer on Saturday afternoon. So I'm hoping and praying (a few fingers crossed too) that all goes well, Tessa behaves and the lady isn't a quack or white trash, and my mom doesn't try to interfere too much with the actual interaction process. A lot to pray for, I know. If you'd like to help too, that'd be much appreciated.
