Stephane: I’m looking for the emergency clinic. Someone told me it was pretty near.
Sean: It’s a stone’s throw away. You see that building fifty feet away?
Stephane: The pink one?
Sean: That’s the one. Just next door.
Stephane: Wow, no kidding! It really is close.
Meaning: "A stone’s throw" means a very short distance; In other words, as far as someone can throw a stone. Most people can’t throw something very far, so when this expression is used, it typically means you’re within sight of a location, thing, or person you’re looking for.
