I despise bullies. I do not really have compassion for anyone that picks on some they figure is weaker than them, this includes animal cruelty.
At the point where they are actively engaging in this type of behaviour, I think they need to be taught a lesson.
My parents were fond of the saying "spare the rod, spoil the child" perhaps a bit over the top, but one cannot allow bullies to carry on unchecked.
I am devastated that you had to experience this horrible behaviour.
Your illustrations are lovely. Be well, stay safe.
