If you never lived in a flat-share, were you even a student for realz? The question doesn’t really have an answer, but it shows one thing. Living with another person under one roof is a one-of-a-kind experience.
And it’s not only about leaving dirty socks in plain sight, bringing in a bunch of friends at 2 am, or borrowing chocolate biscuits with 0.001% intention to return them. Whichever side you were, or currently are, standing on, you probably feel right and the other person is most likely wrong.
But in the land of flat- and house-sharing, there are no right or wrong people, there’s only a nasty-meter that goes up every single time you put an empty pack of ice cream back to rest in the freezer. Call it an exaggeration, but god is in the details when it comes to flat-sharing.
