All week, I've promised myself chores will be done. Mom's words about my defense mechanism are blaring in my subconscious ear. Walls! Walls! Walls! Why can't I tear them down? Why must I always put them up, between people, responsibilities, opportunities, love. Everything in my life is about building this room, this barricade, this mental cave, where nobody may enter, but me. The problem is that while protecting me from the outside, I am helpless to the dangers from within.
