You have to know Pittsburg California and the community mix of races. The other children bring ostracized attitudes and constantly make others feel unwelcome. If someone is suffering from low self esteem the cover of a hoodie feels comfortable. Society not caring that these pressures exist among citizens and peer pressure being what it is. Will cause otherwise good mannered children, young adults as well as older adults to yell out, not feel comfortable. Be frustrated etc.
When feeling attacked. The reaction of aggressive defenses acting uncooperative, exhibiting behaviors that others immediately deem unacceptable can materialize. Then too others will attempt to try others. To satisfy their own shortcomings.
I raised my children to understand these challenges and to turn them away. Not allow peer pressure to dictate anything they do, don't do and participate in. Teach the children this. A bully bullies certain people because they are threatened by them in some manner. In reality there is a quality something about that other child they like or admire. I handled all my bullies in that manner.
I told my bullies and others within listening distance.
If you have all this time to bother me. What is it? You like me don't you? Well everyone hearing that. Shuts down bullying, peer pressure and intimidation immediately.
