Suppose you’re in an apartment with thin walls separating units.
One of them decides to have thunderously loud sex.
If you’re being disturbed, don’t knock on their door.
Instead, record the rumpus.
Play the recording loudly on the next night.
Cheer them on.
Shout it through the wall. I’m sure they’ll take note of it.
Ask if the condom is still intact and in the right place.
