The Wall mostly represents separating or organizing distance to either people, land, or territory but when puts in communication, Wall represents a Barrier to most peoples conversations because the purpose of the Barrier is to Block and Affect the flow of communication, based on my learning they’re different types of barriers but the one we are talking right now is the common type of barrier which its just separate peoples thoughts and ability to speak to one another. Yeah we know it’s a large border to us but every border can be conquered there’s always a way of overcoming this, imagine you’re talking to someone but something or someone is blocking you, you just either need to say excuse or force that thing to stop interrupting your conversation with a person or you might want to something to either understand the person or to show respect to a person in a polite way. The wall is purposely created to be climbed or separate that’s why the people if they seek freedom they have to climb it so that they can be free and somehow the wall is used to keep bad things at a distance so imagine in communication that’s just the purpose of the Barrier it is just a way of interrupting one's conversation.
