I've said this before but there is nothing normal about bullying. Nothing normal or acceptable about a child being bullied, or being a bully. (sometimes I've found the child who is described as "bullied" is, in fact, a bully themselves... bullies can be very socially isolated)
I've had tough guy parents roll their eyes about my concern for the social well being of my students thinking I'm being unreasonable in expecting a school to be a SAFE SPACE.
