I feel so bad about myself because my boy's friend hit my boy. I spoke with the principal and I told him that not every school has the program that he needs. My son's friend has problems but the school doesn't help. I felt like I did bad, saying what I said. I never said he needs to leave the school, I said that not every school has the program for each kid.
You didn't do anything wrong. You notified the school that they have a student who is behaving improperly. They took the action they felt was necessary. That was their choice, not yours.
