Or you could do what I did in a similiar situation. I play the guitar (albeit badly) so I have recording software, microphones etc to hand. The guy who lived in the apt above me had a screamer of a g/f...he got home one afternoon and they got to it (as you do). I'd just finished a week of nights and got woken by the noise. Wasnt too happy as a: I'd been woken up, and b: I wasnt getting any......sooooo.......microph
one, extendable stand, window, and hit record......got a few mins of active screaming, got rid of the background noise, found a really really nice song to mix it into.......cut to disc.....and waited for them to come down. Heard them coming down the stairs, went out and presented the cd to her, with the words, you'll enjoy this one............once they'd come back from the shop, plopped the cd in the player....and turned it up...........I've never never seen anyone so embarrassed, but they didnt make so much noise in future.........
Every single time I saw her after that (till they split up), for some strange reason, had the urge to giggle............
