Well this response I can better respond to, as the last one was a personal attack and this one is you sharing your thoughts indeed. I have come to understand the true meaning of peace in cohabitation (to this point at least), and respecting certain common-sense social norms is one of the best ways to keep a bit of that serenity. Most people (fairly) get irksome if they are put through a similar situation, imagine you're sitting in wherever, and you hear a group of people laughing loudly, interrupting your own flow of telling a story to your friend or that (scientifically proven) level of noise you can handle while keeping a peaceful and cozy vibe? I absolutely do not encourage speaking up against it to the 'laughers' or even dissing them with the ones you're sitting with, but if you are really honest about not being irritated at all by that, you're not such a common case, good for you, but not so good for the rest of us who enjoy common-sense volume in public. Thanks again (honestly and nicely this time :) ).
