He cared

So my wife has turned into a pretty proficient blogger, and entertaining to boot.  So can I do it every day for a month?

Mr. Mortimer, to let us breathe from being smothered in high school trigonometry, had talks.  During class, he looks at a kid and says, "What number?"  Looking down a list, he matches the number to his list of prepared talks and off we went.  To the physics of a toboggan slide, economics of the bowling alley to anything else that vagely had to do with math of some sort.  Now much time did he spend preparing these?  But more vexing, why?

I think he cared.  Cared about things enough to think about these subjects, investigate them, and actually write is thoughts down.  And then fed them to a captive audience who were happy to not be talking about trig.  I can't imagine that he gave these talks to adults (maybe he was a closet Toastmaster?), so I am sticking with the fact that he cared and needed an outlet.
