You, the Landlord, have to inform, your normally model tenant, that you've received a noise complaint against her. A bit of awkwardness ensues as you explain that it may be her headboard knocking or thumping against the wall shared by her neighbour in the bedroom. Your tenant doesn't want to disturb anyone, but wasn't aware of her headboard making any noise - and she wants to prove it to you! It's quite warm in the apartment and she is wearing a skimpy little romper, and as she bounces around on the bed, it rides up and falls down in all the right places. She now enlists you to help her in recreating some of the motions which might lead to a thumping headboard.
