When they finish you should clap and cheer and say good job! Then return the favor- you know they were up late, so around 6am start with moaning and noise and the headboard banging the wall, put on a show for them. I can see it now, standing next to your bed slamming the headboard into the wall, making all kinds of noise. Be an actress! Or, get a porno, crank it up and bang the headboard against the wall. Every single day at the most inopportune times for them.
