I live in a small residential block in a quiet bit of west London. During the summer an absolute arsehole moved in downstairs. He is about 20, doesn't work, doesn't study, and has become the bane of my life. Chief among his many offences is noise; he favours music of the 'urban' persuasion at any time of the day or night. Because his shit-headed mates all still live with their parents they are there all the fucking time, listening to this dreadful cacophony, getting off their heads on skunk and shouting over said music. I've done the adult thing and knocked on his door a couple of times to talk it over with him; as it happens he's not personally unpleasant, but it made bugger-all difference. I've become steadily less friendly, moving through stamping on the floor to complaining to the building manager, who sympathises but can't do much beyond passing on my grievances to the letting agent and landlord involved. Classic noise-based retaliation is out; I can't go to work leaving the stereo to play Wagner on repeat because it would bother the lady upstairs, who is quiet as a church mouse. What should I do? Angles of attack include his copious drug use and the fact, recently discovered, that he is on JSA and housing benefit (I'd previously assumed his parents paid his rent). Humourous/abusive replies expected, but if anyone knows a legal, vindictive means of getting even I'd love to hear it.
