Something happened very quickly at some point, as there was an official letter from the principal (CEO as he calls himself).
This led to us and most parents assuming that they were sent to quarantine.
I'm assuming there was some last minute negotiations and buses were turned around?
And weird enough the school has not sent out a letter explaining what happened.
This remains the last thing we've seen, unless the new letter was marked - confidential and we will expel your kids you leak this letter.
What is probably happened - they are keeping this quiet and the quarantine order is pending the full class getting a negative result.
