I once went riding on this big grey thing that was several times larger than me and knew it. I'd managed to perch myself on top of it, facing the right way which was a bonus. Okay, so horsey wants to eat. Fine, so I sit there while my new equine friend munches away at the foliage.
"Kick it!" yells someone, so I do. Nothing happens.
"Kick it harder!" they yell. Feeling very bad for inflicting pain on the horse I give it a decent whack with my heels and it decides to move. For all of ten yards before it spots a delicious looking patch of grass and proceedes to munch again.
Said horse was feeling very antisocial as it attempted to kick another horse nearby, but I managed to steer it out of trouble. After a very bumpy ride, I get off, thank it for it's time and am promptly ignored until I present it with some fresh green grass to eat, when it's eyes light up and it greets me like a long lost friend.
I'm somewhat troubled by the size and condition of the dangerous looking teeth suddenly bared in my direction, which someone interprets as "Aww, horsey just wants his gums rubbed". Sorry, but horsey can rub his own damn gums until he goes and gets his breath attended to.
