We build a little wall first—just tall enough so that when we venture out (into the sometimes scary world), we can turn around, run fast, jump over it, get really “small” and hide behind it. It’s the “level 1 protection wall” built from something like sand or leaves (sad, lonely). If we have to jump over that wall often enough, we end up creating a sturdier divider. This “level 2 protection wall” is made of materials like brick or wood (bullied, wounded). It still allows us to venture out into the world, but now we have to climb over it to safety. When we’ve had to retreat behind wall number 2 long enough, we finally build the “level 3 protection wall”. This one is serious stuff, an impenetrable structure that no one is getting through! It’s made of steel or concrete (scarred, crushed) and reinforced with pain and abandonment.
