"What'cha doin'?" or "There is no hope. You might as well give up. You're going to die." or "Come out with your hands up. We've got the place surrounded." and so on.
Sending is a targeted spell, so if it had a saving throw, you'd know if it worked. However, it does not, so it becomes a matter of interpreting whether or not "knowing if a targeted spell works" is an inherent function of casting targeted magic, or an inherent function of a targeted spell having a saving throw. Hmm...SRD said:Succeeding on a Saving Throw
A creature that successfully saves against a spell that has no obvious physical effects feels a hostile force or a tingle, but cannot deduce the exact nature of the attack. Likewise, if a creature’s saving throw succeeds against a targeted spell you sense that the spell has failed. You do not sense when creatures succeed on saves against effect and area spells.
