[WonderWhat]

When we first lived together we had a small apartment on a fifth floor, the topmost of the building. We usually had sex at least once a day, and were pretty consistent about closing the windows because we tend to be pretty vocal. Nevertheless, we always left the bathroom window open to avoid mold, and just shut the door to the bathroom.

Fast-forward one year when we were moving out.

I went down to throw a bag of stuff into the car which was parked right under the bathroom window, below the interior light-well with all the windows of the kitchens, bathrooms and master bedrooms of all the apartments.

Suddenly I hear a familiar cough. "My wife's got a nasty cough to hear it all the way down from here from the bedroom," I thought.

I went upstairs and asked her how she was feeling. "Why?," she said "It's just that my throat was dry." And coughed at a pretty low volume to illustrate.

The bedroom window was closed, and the bathroom door too, but we noticed the space between the door and the floor, and that the bathroom window, a casement window that swung out from the bottom, was open and it echoed every small noise from the bedroom down the light-well. A trick of acoustics we wish we'd known about sooner.

We'd been giving the neighbors audio shows at all times of the day for a year. No wonder they were either all smiles or all frowns when we met in the hallways.
