Build the Imperfection

Yep, the world economy hasn't improved much so in my dream, I took a job at a construction site. We were to undergo training in building methods and we were to start by installing doors. We watched as two teams worked on a trial wall. One team set the door frame a bit too low and the other team set the door frame way too high. Our team was supposed to go next but the whistle went off which meant...lunch time.
