on the first day of "wood shop" in 1965, the shop teacher passed around a piece of wood, and everyone got a sheet of
paper, an envelope and a pencil
everyone was told to take as long as you need, it was critical to get an exact measurement...
then you signed your name and sealed the envelope
everyone had already answered the question: OF COURSE I KNOW HOW TO USE A TAPE MEASURE
i learned a lot that day
