They have a loud party going on in the house across the street. Past 22h, they should not be so loud.
I happen to know they play music from youtube and spotify. I also happen to know their WiFi password, and can easily MitM them from the comfort of my room.
If they wake my babies, they'll be playing MY kind of music. Say hello to some sweet Skinny Puppy, Cradle of Filth, Nine Inch Nails playlist.
(They're... not going to be happy about this playlist)
