Why do we let strangers in?

       We are human, we get hurt. I can promise every one of us has heard to not talk to strangers. So why do we let them in? If the skin resembles someone we knew, we let them in, into our minds we tell them things about us opening a door to get hurt, but why do we do this? Some of us want to get hurt, and others are magnets. Without pain we don't learn and we walk around like a shadow just trying to fallow the object it resembles. With pain we find hope in ourselfs to break free from the object we once were. We need pain, but it hurts to have it. My brother is a object it only knows to cause pain, making my Mother and Grandmother fight, tying me in the middle of it, some how. I don't consider him to be human, or my brother in particular, because a normal person can't see those things splitting two people apart. The object that he reflects is named Drugs, he follows where ever it leads. My Grandmother is a nurturer doing what she things is best for her family, yet she still hasn't come to terms that what she thinks is best is the worst thing she could be doing besides buying the Drugs for him. That nurturer in her is making her push farther and farther from my Mom and Me. My Grandmother an my Mom keep hoping for the best, my Mom knows she can't do anything. I know that's not my brother, just a stranger with the correct ID and name just a demon wearing his skin. Call me harsh for this and for those of you who don't understand and think shamefully on me picture this. You constantly come home from a good day to discover your Mom crying, now picture that happening for months, years even you would grow sick of the tears you can see through all of his lies and you know better but know one else wants to listen. Hatred would to grow in your heart. Until you couldn't take it. My brothers a complete Stranger yet my Mom and Grandmother choose to let them in and hurt them. Is it a lesson for me or for someone else?
