I adore this thread.
My gelding can be kind of stupid spooky sometimes. Last night, he was jumping at any kind of noise, snorting, acting up, wouldn't collect at all because he was too busy prancing around. Last week, he was perfect. He was calm, acting like such a gentleman for me and trying so hard to be perfect.
Horses are very unpredictable. Granted, I know why he has been hyper and spooky lately, but still. Non-horsey people need to realise that horses are NOT push-button animals. The deadest-broke horse can still have a meltdown if given the right circumstances. They are beautiful, dangerous, powerful creatures with minds of their own. They can be fine one moment, and downright insane the next if something sets them off. The second you assume something about your horse, he or she does something that keeps you on your toes. Non-horsey people, not all, but some, ought to show horses the respect they deserve. Then they would understand why we love them so much and just how crazy it is that we team up and bond with them. :)
