Each and every person who has ever shown has been embarressed one time or another!
My first story is when I first started showing, and I was in a showmanship class with a herd bound horse. It went TERRIBLE! Every forward movement would be a prance with added neighing for his buddy. When we stopped for the judge and set up, he stretched out his neck towards her face and blew all of his snot right into her face! She was very displeased, but I ended the pattern with a smile on my face!
