Do you know the expression, "A nod is as good as a wink to a blind horse?" I don't get this expression at all.
1. Why are you winking or nodding at a horse? Is the horse an undercover spy that you are trying to communicate with?
2. If you are riding the horse, why don't you just say "Whoa!"?
3. Why are you riding a blind horse? Even if winking or nodding did anything, he's blind!
Oh, and 4. Don't we shoot horses when they go blind?
