I later overheard my neighbor lamenting about his lost duck
That's a shocker. How did he lose his duck?
Don't ask me I don't know. He seems like a weirdo
It is okay to be curious about others and wanting to know more about them. But you should not listen in on a conversation that does not concern you.
Nah I love the sound of their voices. I just love listening to other people and being interested in them.
It's wonderful you enjoy candid conversations, but it's still a little rude to eavesdrop like that. How about going to a more public place like a park, where everything is intended to be out in the open? There will be a lot more voices for you to enjoy too!
