If you charged $450.00 for you’re course they wouldn’t have said a word. I raised, bred and showed Arabian horses for 30 years and found out that the more you ask for the more you and you’re animal was respected. When I first started out and gave much lower prices, trying to help the buyer also or so I thought but I soon learned that the horse was not treated the way it should be. Long story short , sometimes it just hurts when you try to help other out.
