My 3dc had a school assembly where they talked about what to do if you get lost.
Please bear in mind this is the translated by the kids version.
If they get lost they should find a lady - preferably who has children, then other ladies, then men, because they arcane be bad.
Aibu to be cross that my boys aged 6 and 4 are being given negative messages about being male. I am also cross that this sounds like "stranger danger" again when children are far more at risk from non-strangers.
Sooooo - aibu to send an email to the head (and suggestions of how to say it much appreciated.
