It's early morning. Builders know this. Tap tap tap. hammer, drill. This continues just long enough to wake those foolish enough to slumber on a day off from the daily rate race.Tap tap tap, hammer and drill.
 And then, as if by magic, they stop, finish, cease their labours. All is quite, all is peaceful. There misssion has been completed. Make enough noise and declare that we are up and working. Then peacefully retreat for tea and a sarnie.
Wonderful.
