Sometimes I enjoy listening to other peoples conversations, listening to the lives of others, their quarrels, their joys, even listening to their funny moments and laughing along. I don’t do it on purpose, I just tend to be observant towards these sort of things. Perhaps it’s because I feel that my current situation isn’t interesting enough and so my focus turns to my surroundings or someone says something that just piques my attention. There’s nothing wrong with listening in, if they didn’t want you to listen it wouldn’t be said out loud or in public.  You can find out so many things: current events, random facts even touching stories. even hearing people talking in another language is a good exercise in learning, such as brushing up on my chinese, picking up or recognizing random phrases of korean or japanese, it’s kind of fun.
