So...

Note the horse on the left side. The red cone outside his stall is apparently to warn people that he bites. (I like the idea, although some horses would destroy the cone as they walk by ;))

So, here comes the guy with the water buckets. Instead of waiting for the other person with the horse to walk past...

...yeah.

You know...

...if there's a warning sign on the pen, pay attention ti it.

The kid ran up to the pony and reached very quickly for her nose. When she had a very young foal. So of course the pony tried to bite her...

Bitey?

Well, that wasn't a serious bite, but...I wonder how well the guy knows that horse.

Actually, it looks a lot like a pony I know who had that habit...

Ah...

...the joys of non-horse people interacting with horses.

The trainer should probably have warned her to move her hand. That was so inevitable.
