The problem with fences, they say, is that not only do they keep some people in, but they keep others out. While this is definitely true, and regarding this principle one should definitely exercise caution, we should not, however, “throw the baby out with the bath water.” While some fences are built to the extreme (i.e. you don’t need a 20 ft fence to keep your dogs in the yard), a properly built fence keeps in the children and pets, keeps out the unwanted solicitors & predators, and maintains a healthy relationship with the neighbors. It’s the same with Torah.
