Not sure why yeast are personified.
Yeast are little biological machines. They have no personality or attitude. They can only react to the environment that you put them in. Pitch enough yeast into healthy, well-aerated wort at the proper temperature and they will act within a predictable timetable. The degree that you
stray from optimal conditions will determine how long your beer takes to finish. Not the mood of your yeast.
