Walls are specifically designed to keep unwanted elements from coming in or out of an area. Much like a cage at the zoo, it keeps people from harassing whatever wildlife that is being kept and it keeps said wildlife from attacking the families at the zoo. It makes a lot of sense when you think about it. Which is why it always would amaze me when people would give me shit for putting a wall up between my emotions and them. Obviously people who put up emotional barriers don’t like being hurt and so they throw this wall up as a way to protect them…. Sometimes that invisible wall is put up to prevent hurting anyone too. No one ever gets that. Life is funny that way.
