You keep a wall up to protect yourself because you don’t want to get hurt.And so you are back behind this wall.Is it really pain-free behind the wall? Doesn’t the loneliness hurt, and doesn’t the fear hurt, and doesn’t the constant turmoil up or down hurt? So it seems to me that if you go behind the wall you are guaranteed to be hurt and if you come out from behind the wall you MIGHT get hurt. You might get hurt from out behind the wall, but as least you have the upside of things
