It makes the difference between what's possible and what's not.
Any reasonably bright person would run afoul of it sooner or later.
The only way to know its a firewall is what happens when you do away with it.
Here and there doesn't mean anything without then and now.
It's all about the boundaries.
It begins with a boundary.
It ends with a boundary.
Self is a boundary
Place is a boundary
Life as we know it is a boundary
Sometime you let anger get the best of you and you cross a boundary you didn't mean to cross.
You can't get it back and you are left with a life you cannot fix
