My ds lives in a shared flat with two other guys. They’re mid twenties and early stage professionals (lawyer/lecturer/diplomat).
My ds is sociable and very clean. Flat mate 1 is also clean and sociable. Flat mate 2 is fairly clean, but extraordinarily extroverted. He constantly has people around the flat for drinks.
Not really an issue for ds and other flatmate as they all get along well. The problem is, flatmate 2 has an extremely loud voice which carries. He also insists on putting music on very loudly.
It’s not the noise for ds himself, but he doesn’t want to annoy the neighbours. Even though they’re purpose built flats, the neighbours must be able to hear things. They’ve only just moved in so no noise complaints yet but ds is dreading one coming.
Flatmate 2 will quiet down a little when told but soon starts to raise the volume again.
