You know it's time for seat changes when every 4th sentence out of your mouth is, "Shhhhhh".
You know it's time to reteach a topic when most of the students got that type of problem wrong on the test.
You know it's time for an ethics discussion when after you hand a test back, a student asks why she got one problem wrong ... and you can see the erasure marks and "revisions" on her test from her freshly updated answer.
You know the school tardy policy is not working when a pack of 15 kids are cutting and roaming the halls yelling and disrupting your class.
It was one of those days. Monday and raining and in the October slump.
