Find this fascinating, why is everyone so sure no teacher would lie ever?
My family are all teachers as are a couple of friends. They are just people!!
There are good and bad and weird and wonderful people in every group and teachers are no different!
Also know a lot of social workers and can think of one who I wouldn’t trust at all.
Saying categorically that no teacher would make anything up is actually dangerous, belongs in same box as -
Nurses never harm babies.
Presidents never grab pussies.
Doctors never purposely kill patients.
Grooming gangs don’t exist.
Governments don’t hold parties during imposed lockdown.
Before anyone suggests I have any motive for questioning this belief, please be assured I have never had a teacher lie about/ to me.
OP, it is highly doubtful the teacher made it up, more likely miscommunication.
I would email the teacher and calmly ask for clarification and also advise the children have seen doctors on this issue.
On another note, I have blisters that appear every few months on toes and fingers.
Doctors haven’t got a clue, just one of those things!
