Just checked my email. Here is the standout message today:

We had 30 attendees this last Saturday for the following reasons: Behavior, not attending detention, not turning in homework and absences.

For each Saturday School that a student attends, they make up one day of missed school and we recover the ADA! (emphasis added)

We try, but with the Bolsheviks having control of our public education system, and the useful idiots falling right in line, we have a way to go before we can right the wrongs.
