Hey, you can lead a horse to water .... but you can't make them see that they're an ass.
A horse should never see itself as an ass because a horse is not an ass and an ass is not a horse. But, me thinks readers get what you're trying to say!
Sorry. Couldn't help myself.
Oh, and a horse that thinks it's an ass, well, I'd say the real asses better watch out, and everyone else should get ready for a mule or hinny!
