Had a call from school. He has insulted another girl in his class several times apparantly. Think another word for prostitute. I am so angry, sad and disappointed in him. He's autistic so I make a lot of allowances for his weird behaviour but this is something else. He knows damn well what it means and that he can never say that word to anyone no matter how triggered he gets. I'm sure he'll come home telling me that she started it but I couldn't care less. He is so out of line that I think I will cancel his birthday party next week. AIBU ?
