If my window shade is broken or magazine pocket is frayed, I wonder what else on the plane has seen better days.
That's why I love airplane bathrooms. I love how they are designed so the light comes on only if you lock the door, ensuring that you'll never forget to lock it. And even if you do forget and someone opens the door, the light is off! The shadow of darkness shields your dignity! Whenever I'm tinkling 35,000 feet over this great Earth I find myself hoping the engines, instrument panels and landing gear were designed with such great forethought.
