I remember when I first switched from CTR to endurance, I was steaming
along on my old Earen, doing our usual humongous trot, and when I passed
someone, she called out "hey, he looks a little hitchy behind, does he feel
okay?" Yes, I was psyched out...I slowed down, told the vet at the next
check. He said everything looked great and this rider did stuff like that
all the time. I was sooo mad. I knew if I confronted her, she'd just
shrug and say it was an honest mistake. I also rode with someone once who
spent the whole day saying she wasn't interested in racing, just wanted finish
the ride, blah blah blah. When we got close to the finish I got off to
walk my horse in, and she took off galloping. Live and learn :-)
