You have to be pretty obvious to get caught, and pretty oblivious to allow people to overhear you when you are talking confidentially.

Us teachers hear a lot of stuff that's not intended for our ears.

On my kids more than once

Nope. I walk right up and say "What's everybody talking about?"
I hate gossip.

I try to shut down the outside noise, but do get caught up in it sometimes

As a kid in adult convos. Never as an adult

The bad thing about eavesdropping is when you secretly hear your name, start paying attention, then learn much later that you are not the only person with your name. See, it wasn't about you after all.

Yes im terrible at it call me Paranoid or curious but it gets me into a lot of trouble , Its even worse when you no they are talking about you and you then hit them up and question them. The usual reply is " I didn't say that your Hearing things" or your a a nosy so n so , Its all said loud enough to hear but quiet enough to say they never did . So one day I tested it out and left my smart phone on record in the cupboard amongst the cornflakes and crackers and let it run. I then chrome cast the whole conversation on to the 54 inch Tv while watching Coro street . Well crikey dick I was not expecting to hear the whole story in detail but it was enough for me to confront the story teller . I was very sweet about it and asked to join in as it was a two women affair , Sadly No her friend was not to keen as her Husband was my old Boss so yeah sometimes it pays to be a little Nosy...

Yes, not good to start a conversation about the conversation of the people behind you at a restaurant. Sometimes they get a bit offended. Seriously though if you're going to have a conversation at a public place, you have to expect that people may listen.

No. I'm relieved to say.

No, I think that I am very good at it. No just kidding. I don't really care what other people say or think about me.

I often eavesdrop on other peoples conversations, even if I don't know them or who they are talking about - sometimes quite humorous (and harmless).

no,
(never been caught) haha,
I wonder why eavesdropping is not considered as bad as peeping?
