Invisible Fence

Is being territorial an unexcusable state of mind or truly just a defense mechanism? Take a look around. We are all building these fences around us. Fences that are pseudo-protecting us from all harm and danger. But are we protecting us or are we protecting everyone else around us from our wicked selves? I refuse to think that there is an invisible barrier between those who we love, and that everytime we try to reach out to them it will emit some sort of shock wave right through our system. That same shock that we get time after time after trials of approaching emotions just to find out how impossible it is to break through that invisible line.
Tough love, folks. But it's still love.
