Dear Bully’s Mom,
If your child is pushing again next week, I will not keep Enzo’s sensory issues in check so when your child goes to push him, he will most likely respond with “fight or flight” mode then maybe your 4 year old will remember not to push Enzo again.

Sincerely,
Enzo’s mom

PS…it doesn’t really matter to me that your child is only 4 especially since your 4 year old is about the same size all the other kids he’s knocking over (on purpose).
