Has someone put up a fence?
Yes, but the fence has a gate, and the gate is unlocked.
It's there to keep the rabid dogs on each side of the fence seperated.
PS Hi Leah! Welcome to the funny farm!
With the eye of wisdom we discover a lot of anger in us, any amount of jealousy, resentment, ignorance, desire - mountains of emotion whose existence we would never have suspected in ourselves... We recognize that most of the faults we perceive in others are only the mirror of our own negativity, the reflection of our own disturbed feelings... At the same time, we relieve the world around us of the burden of our own negative judgements."
