a friend of mine stays at her boyfriend's studio practically every night... we were drinking red wine last week and she told me that she's been really tired lately.. every 6.30am at her boyfriends, there will be a full 20 seconds of headboards banging against the wall. they couldn't figure which apartment it's coming from. the first 15 seconds will be slow banging, and the last 5 will be superjet fast banging, on the 21st second there will be a soft "ahhhh..". my friend, of course, is awakened every morning at exactly 6.30am. again one night she went to her boyfriend's and the banging started at 11.30 and lasted for 20 seconds. 20 seconds. again, the soft "ahhhh.." follows..and the next morning again at 6.30am the banging starts and ends after 20 seconds with another "ahhh...". she got so mad that she complained about people having sex for 20 seconds to the management. the management had a hard time finding out which apartment it was because technically they couldn't knock at the door and ask "who's the 20-second guy?????" NOTE: throughout the 2 weeks that her bf has been living in that complex, apart from that "ahhh..." (a man's voice)..she has tried hard to figure out whether he's just giving himself a good treat, or that he's playing with plasticky jen because..she tried so hard to figure out whether there was actually a female partner, and decided against that. :s What would you do in this situation?
