BIG things were happening in my life the summer after I turned 13. In the middle of that summer, my parents     my entire world when they told me they were getting divorced. I couldn’t believe that our family was going to     . Though I always knew my parents weren’t very happy and they often fought, I still wanted my family to stay       .
My life changed completely after the divorce. My mother and I moved into a small apartment       town, while my father and brother, Bill, stayed in our house. I now became a visitor       I went to see my Dad and Bill on the weekends. And immediately I had my stepfather, Dan,        I showed no interest in. I was clearly sad, especially after Dan and my mother married       I realized that there was no way that things could change       the way they were.
Even though I refuse all Dan’s trying to get to know me and wasn’t very nice to him, he never gave      on me. Gradually, I began to trust him. I realized that we actually had some things in common, especially when    came to movies and TV shows. We spent a lot of time together    out to watch movies. That gave us a chance to talk and get to know each other    .
Better still, Dan showed an interest in me that I had       experienced from my own father. Dan was always around when I needed       on school or friends. Once I began to         Dan, the three of us began spending a lot of time together. We often went out to eat and       short trips. Eventually, I discovered that I finally had the happy family that I had always      .
I now realize my parents were       about getting the divorce. Their breakup was the best thing to happen for all of us. My father also found happiness—he       and had another child, my half-sister, Michelle.
At 13, I       an important truth –change is not always the worst thing that can happen. Sometimes, it is just what we need most.
