My late mum adored eavesdropping. Unfortunately, she was hard of hearing, which was not a good combination.............. We were in a cafe, many moons ago, and I was in the middle of telling her something when she went "Shush!" (note - like many hard of hearing people, she spoke very loudly....) She then went on to tell me - and whole cafe - about the "woman in the green coat behind her and her recent operation"
Another time, another cafe, she was so intent on leaning back in her chair to hear the women behind her that she tipped her chair over and landed flat on her back in the middle of the cafe. Luckily she wasn't hurt, but that still didn't stop her!
