Today's reminder not to complain came from one of my students, a normal 18-20 year old girl.  She wrote me an email in which she apologized for missing class BECAUSE HER PACEMAKER WAS MALFUNCTIONING.  I'm sure its a very scary situation, but her email was very cool and collected like it was no big deal.  I take back everything I have complained about in the last month and apologize for complaining in the first place.  My bad.
