He was listening to my conversation with the old man but didn't say anything.

"You can listen to my conversation and read the letter."

In which case he might, at that very moment, be listening to their conversation.

"But you don't know who else might have been listening to your conversation."

The chief was standing right by the door, listening to the entire conversation.

"And I was brought up not to listen to other people's private conversations."

I love listening to their little conversations they have together.

His men had followed him out and they were standing around listening to our conversation.

He had listened to the conversation on the other side of the door.

He seemed to be unable to listen to the conversation.
