Time redefined

I was just killing time talking with Mr. Sweater (History) and the subject turned to evaluations. He was being evaluated this month sometime and was looking forward to it (?!?). He then threw me for a real loop.

"I haven't been evaluated for at least three principals, maybe four. I'll have to go and look."

How about that? We've had so many that it's easier to discern which year not by the kids who were there (Sam's older brother's year - you know, when they decorated the ...) but rather by the principal. Oh, and this measurement system is more fine-grained than doing it by year, too.
