Why I'm Tired All the Time

I teach English, not math, but a lot of my days look like this:

So today we studied the Greek root CYCL, which means circle. Cycl is a root used in the word cyclone.



"Who can tell me what a cyclone is?" One little darling's hand shot up high.

"It's someone who looks just like you, like an identical twin."

Multiplicity

 And that's why I'm tired all the time.
