Big things were happening in my life the summer after I turned 13. In the middle of that summer, my parents   小题1:  my entire world and turned it upside down   小题2:  they told me they were getting a divorce. I couldn’t believe that our family was going to   小题3:. Though I always knew my parents weren’t very happy and they often   小题4: , I still wanted my family to stay the same.
My life changed completely   小题5:  the divorce. My mother and I moved into a small apartment across town,   小题6:  my father and brother, Bill, stayed in our house. I now became a   小题7:  whenever I went to see my dad and Bill on the weekends. And immediately I had my soon-to-be stepfather, Dan, whom I showed no   小题8:  in. I was depressed, especially after Dan and my mother married and I realized that there was no   小题9:  that things could change back to the way they were.
Even though I  小题10: all Dan’s attempts to get to know me and wasn’t very   小题11:  to him, he never gave up on me.  小题12:, I began to trust him.

Once I began to warm up to Dan, the three of us began spending a lot of time together. We often went out to eat and took short trips.   小题16:, I discovered that I had the happy family that I had always wanted.
I now realize my parents were  小题17:  about getting the divorce. Their divorce was the best thing to happen for all of us. My father also found happiness—he   小题18:  and had another child, my half-sister, Michelle.
At 13, I learned an important   小题19:  —change is not always the worst thing that can   小题20: . Sometimes, it is just what we need the most.
