I work evenings until 11 or 12 so I have to go to sleep and wake up a little later than someone on a 9-5 schedule. Our downstairs neighbors, not for the first time, woke me up this morning (about 9.30) playing music so loud that my bed was literally shaking.
The way to deal with this inconvenient annoyance, which I hadn't thought of when it has happened in the past when I was wide awake already, is to shout 'SHUT UP' as loud as you can while still half asleep. Music went right down. I'm not proud but I might keep this in my back pocket for next time, if there is a next time.
