My house has pretty thin walls.

It's probably the quality of construction or the materials used when the house was originally built. I'm frequently frustrated with the way sound travels in the house, particularly because my wife goes to sleep a lot earlier than I do, which means that I have to be pretty careful about how loud I am after ten o’clock or so.

Just now Melissa was singing in the shower. She rarely sings without me prompting her to, but she's performing for a friends piano recital later today and I think she's still a touch nervous. Her voice, the mood of the song and the tone of her vibrato lept right through the walls of our home to where I was sitting in the living room.

It was remarkable. Thank goodness these walls are so thin.
