Why would one wants to build a 'wall' to relationship? To block yourself from being loved or afraid of loving? Something i am still figuring, apparently the closer you are to the person the higher the wall is built, in order not to let the wall break through. Well, it is definitely a choice and the result of the choice is something need to be measured. There can never be a 1-way minded communication, not even in God's context. God loved us first so that we can love Him, however a relationship cannot grow with only God loving us and we not loving God.
