You have to filter what your kids see as adults... it our job. Its our job to try the best we can to expose them to the world at the rate they can handle it.. not at the rate that it might happen. We cant stop the curve balls, but we can prepare them for when they happen. Too many parents are eliminating that filter and as a result we have kids that are desensatised to murder, death, war etc.
Granted its more the schools fault for their slow emails, but it would have been nice to know what he was saying before it was said.
Parents that dont try to filter what their kids see/hear/do based on their comprehention level are failures as parents.. period.
