Much of day-to-day life involves the knowledge (and practice) of unspoken rules. For example, here in New York, you should not be putting a bag on a subway seat – and you should definitely let people get off the subway before you get on. They may seem like universal forms of etiquette, but more people seem to ignore them than we think. Recently, redditor u/HAXposed asked the site’s users to share the unspoken rules that, when broken, annoy them the most. And it’s sad but validating to see that most people are, in fact, annoyed when people play music on their phones in public. While that one definitely had us nodding in agreement, the rest are just as relatable. And annoying.
