From what I have read lately, the teachers have been complicit in some cases. Not surprising, when the quality of education, including that of education majors, is on the skids.

Way back in 1967 I was the bullied one in 7th grade. Did me no good at all to tell teachers, who saw it happening any way. Nothing was done to stop it. I just rode it out.
