Florence, im going to rltty again to help.you understand why it's inappropriate to relate this to real world bullying, by using a real world example as you insist on doing:
The game of football(soccer), in the playground (because you always reference children for some reason. I thought it was mostly 40yrolds that played this not nine year olds but maybe I'm wrong).
One of the things you can do in a game of football is score goals. Another one is defend. Both are valid enterprises.
If one nine year old decides that another nine year old scoring against him is bullying, does that mean it is? All adult rationale says no. However, that nine year old child may be very upset and cry and be convinced the other one has bullied him by scoring a goal. This is understandable because he is a child and hasn't yet had time to fully appreciate that they are not the center of the galaxy.
The child that scored may feel a bit sorry for him, he may not, he may be just happy with experiencing the game of football.
No one decides that he is a bully do they?
