My year 6 daughter has a school friend who has decided she is a therian, wants them all to pander to it, call her hands paws when they are together, etc. She’s a nice girl with nice parents, but my daughter says her parents have no idea about it all. Some of the chats from her are very teen angst and melodramatic. It does present as being an attention seeking strategy but a little manipulative in how she expects the others to bend reality to affirm her status as an animal in human clothing so to speak.
If it was my daughter I would really want to know about it so I could address it, but I don’t know this mother well and would rather not create tension at the school gate.
Yabu- don’t tell the mother. Maybe she knows, or you’ll start a drama
yanbu- tell the mother, give her a chance to address it
