I used the following line in a new story, where "Phil" is in a separate room from the person he's speaking to (via bluetooth earphones).
"All right," Phil nudged her, speaking in her ear, "everyone's waiting."
Am I nuts using "nudge" as "prompt" while many readers may read it as "poke", or do you think readers are smart enough to understand what I'm saying?
After all, it's not like he can physically nudge her from another room.
