So I keep three horses at the barn that I work for. It's been about...two years since I've had to leave them longer than two or three days. Before that, I'd always had one person who also works with me 'horse sit' them for me. She's a decent rider, she's known my horses for awhile and I trust her. However, she was horse sitting when I only had two horses. I have since gotten Cash, a thoroughbred (never raced) who never the less is a very big handful.
My previous horse sitter didn't really have a problem with my other guys (Scribbles and Rambo) as Rambo is really a push button horse, very talented but just a very easy ride. Scribbles can be a little stubborn and he's big so he's strong, but I can fairly easily teach people how he likes to be ridden and he goes fine. I REALLY am not comfortable with her abilities with Cash though. I think he's too much horse for her, and he's not the kind of horse I can leave for a week without him getting worked under saddle at all.
Because of this, I've asked one of my students to horse sit for me. She's actually a fair bit younger than the girl I work with, but she's a VERY talented rider and extremely mature for her age. She's ridden Cash before and handles him very well. Though she's never been on Scribbles or Rambo I have no doubt she can ride them. My problem is this, my previous sitter has caught wind that I'm 'replacing' her with a younger rider she doesn't seem to believe is better than she is. I've tried telling her that it's only because Sterling (student) has ridden Cash before, not neccesarily that I look down on her riding abilities, as I'm trying to stay polite.
She's worked for the barn longer than I have, and is a bit more favored by the boss than I am (she sells horses, even if they're sometimes out of their riders league; while I'm really not that aggressive selling wise) and having bad blood between us really isn't good. I'm a bit at a loss for what to do :\
