Oskar and blacks

Oskar is going on a journey and trying to find the lock that fits this black key mystery. I realized that this is his coping mechanism to his dad's death. He finds the comfort in talking to total strangers and just opening up his life to them. For example, Mr. Black in 6A made him think about life. I feel like he finds more comfort with talking to the blacks then talking to his mom. His mom plays this very distant role and when she tries to play the role of mom Oskar doesn't know how to react because she never does. The death has presumably affected both of these lives. I have noticed that the mom just seems to want to move on and just go on with life. But Oskar trying to find the black key mystery is his way of getting through this tragedy. He finds happiness in Saturdays because finding the black key is happiness to him.
