Before installing drywall, stand back and survey your addition. Take a close look at the wires running through the walls, at the plumbing pipes spanning the underside of your floors and at the insulation stuffed between studs. Unless you have done something dreadfully wrong, this process will swell your ego with pride, and give you confidence to continue your work. You might want to consider hiring a professional photographer to memorialize this scene because, barring a natural disaster, you should never again see the frame or the inner workings of the house.
As the photographer goes about his business, have him take a shot of you raising a hammer to those rugged looking walls in the corner of the bathroom.
Instead of a smile, the sight of this corner might spur you to think about how the wallboard will hang from those sturdy studs. Will you frown contemplatively?
The photographer will insist on a happier pose. As merry as you were only moments before, you will wave him off; it dawns on you that you are not quite as done with the addition's frame as you had thought.
Two weeks later, you will receive a package containing a bill and a flattering photo. With an insulated wall as a backdrop, the picture shows you bent over, looking for a scrap 2X4.
Over your protests, your wife will hang the photo over the sofa with the other family pictures. She will say it shows your good side. You'll just be glad your pants weren't riding low that day.
